Tagged: msi, gtx 770, GK104, gk-104, gaming, factory overclocked, 4GB
MSI recently announced the GTX 770 Gaming 4GB which combines a factory overclocked GK-104 GPU with 4GB of GDDR5 memory and the company’s Twin Frozr IV cooler on a custom PCB. This card joins the existing MSI GTX 770 with 2GB of memory in the company’s GPU lineup.
Specifications the new graphics card include a GK-104 based GTX 770 GPU with a base clock of 1137 MHz and a GPU Boost clockspeed of 1189 MHz. This compares to the 4GB Zotac GTX 770’s base and boost clockspeeds of 1059 MHz and 1098 MHz and to the reference NVIDIA GTX 770’s 1046 MHz base and 1085 MHz boost. In short, the upcoming MSI card is one of the fastest-clocked models with 4GB of memory. Unfortunately, that 4GB of GDDR5 does not come factory overclocked, and is instead left at the stock 7 GHz clockspeed.
Further, the MSI card is cooled by the company’s Twin Frozr IV cooler. This HSF features two 100mm fans that cool an aluminum fin stack. In turn, that fin stack attaches to the GPU block via five heatpipes. There is no backplate, but the card does have a reinforcing plate between the PCB and cooler (which also, likely, helps dissipate a small bit of the heat generated by the VRMs and RAM).
The card is essentially the same card as the existing 2GB version, which is not necessarily a bad thing. The model number on the 4GB card is N770 TF 4GD5/OC. MSI has not released pricing or availability, but expect it to be around $430 and up for grabs later this summer.
More photos of the upcoming 4GB GTX 770 GPU can be found over at TPU.

Tagged: powercolor, devil hd 7870, hd 7870, amd, GCN
Nearly a year ago, PowerColor launched the massive “Devil 13” Radeon HD 7990 graphics card. Now, the company is releasing a new Devil-series single GPU card called the Devil HD 7870. This card combines a huge dual slot, triple fan HSF with a factory overclocked Graphics Core Next-based Radeon HD 7870 GPU.
The upcoming Devil HD 7870 features a factory overclocked 7870 “Pitcairn” GPU clocked at 1100 MHz and 2GB of GDDR5 clocked at 1250 MHz. As a refresher, the 7870 has 1,280 stream processors, 80 Texture Units, and 32 ROPs along with a 256-bit memory bus. The reference AMD Radeon HD 7870 graphics card has a GPU clockspeed of 1000 MHz and memory clockspeed of 1200 MHz.
To differentiate its card, PowerColor is pairing the factory overclocked GPU and memory with a triple fan (four heatpipe and aluminum fin stack) cooler similar in design to the Devil 13’s HSF. The card also features PowerColor’s “Platinum Power Kit” which entails a 7+1+1 power phase with digital VRMs and so-called “Super Capacitors.” PowerColor claims that its triple fan cooler runs 25% cooler and 18% quieter than the reference AMD cooler.
The Devil HD 7870 offers up a DL-DVI, DVI, HDMI, and two Mini-DisplayPort video outputs. It is powered by two 6-pin PCI-E power connectors.
There is no word on pricing or availability, but expect the Devil-branded card to come at a premium (possibly around $270 MSRP).

Tagged: sapphire, hd 7730, GCN, cape verde le, cape verde, 7730
Sapphire has launched its own budget card based on AMD’s Cape Verde LE GPU called the HD 7730. In fact, Sapphire is launching two 7730 SKUs with differing amounts (and types) of on board memory. Specifically, Sapphire is launching a Radeon HD 7730 with 1GB of GDDR5 and a HD 7730 with 2GB of GDDR3 (yes, you read that correctly, the second SKU comes with 2GB of GDDR3 memory).
The HD 7730 is based on the Cape Verde LE GPU, which is similar to the Cape Verde chip used in the 7750 and 7770 graphics cards minus a set of stream processors. The Graphics Core Next-based HD 7730 comes with 384 stream processors clocked at 800 MHz and 128-bit memory bus. From here, the two SKUs differ. One Sapphire card comes with 1GB of GDDR5 clocked at 4500 MHz while the other version comes equipped with 2GB of GDDR3 clocked at 1800 MHz.
For comparison, the HD 7750 comes with 512 stream processors clocked at 800 MHz.
Both Sapphire 7730 graphics cards come with the same dual slot, single fan cooler. Also, both cards support one HDMI, one DVI, and one VGA video output. The cards measure 168 x 104 x 33mm and have a 47W TDP.
Sapphire has not yet announced US pricing or availability, but various sites around the web report that the cards will each cost approximately 70 Euros. That works out to about $91 USD. Unfortunately, that price will likely be hard to justify considering users can pick up a noticeably faster HD 7750 for around that same price. Users building a new system looking for similar GPU specs to the HD 7730 may also wish to look into building a system around AMD’s APUs and skip needing a dedicated card altogether.
You can find more specifications and photos on the Sapphire website. Both cards are listed on the site and can be selected via the filtering options.
Overclocked GTX 770 from Galaxy
When NVIDIA launched the GeForce GTX 770 at the very end of May, we started to get in some retail samples from companies like Galaxy. While our initial review looked at the reference models, other add-in card vendors are putting their own unique touch on the latest GK104 offering and Galaxy was kind enough to send us their GeForce GTX 770 2GB GC model that uses a unique, more efficient cooler design and also runs at overclocked frequencies.
If you haven't yet read up on the GTX 770 GPU, you should probably stop by my first review of the GTX 770 to see what information you are missing out on. Essentially, the GTX 770 is a full-spec GK104 Kepler GPU running at higher clocks (both core and memory speeds) compared to the original GTX 680. The new reference clocks for the GTX 770 were 1046 MHz base clock, 1085 MHz Boost clock and a nice increase to 7.0 GHz memory speeds.
Galaxy GeForce GTX 770 2GB GC Specs
The Galaxy GC model is overclocked with a new base clock setting of 1111 MHz and a higher Boost clock of 1163 MHz; both are about 6.5-7.0% higher than the original clocks. Galaxy has left the memory speeds alone though keeping them running at 7.0 GHz effectively.
Another Wrench – GeForce GTX 760M Results
Just recently, I evaluated some of the current processor-integrated graphics options from our new Frame Rating performance metric. The results were very interesting, proving Intel has done some great work with its new HD 5000 graphics option for Ultrabooks. You might have noticed that the MSI GE40 didn’t just come with the integrated HD 4600 graphics but also included a discrete NVIDIA GeForce GTX 760M, on-board. While that previous article was to focus on the integrated graphics of Haswell, Trinity, and Richland, I did find some noteworthy results with the GTX 760M that I wanted to investigate and present.
The MSI GE40 is a new Haswell-based notebook that includes the Core i7-4702MQ quad-core processor and Intel HD 4600 graphics. Along with it MSI has included the Kepler architecture GeForce GTX 760M discrete GPU.
This GPU offers 768 CUDA cores running at a 657 MHz base clock but can stretch higher with GPU Boost technology. It is configured with 2GB of GDDR5 memory running at 2.0 GHz.
If you didn’t read the previous integrated graphics article, linked above, you’re going to have some of the data presented there spoiled and so you might want to get a baseline of information by getting through that first. Also, remember that we are using our Frame Rating performance evaluation system for this testing – a key differentiator from most other mobile GPU testing. And in fact it is that difference that allowed us to spot an interesting issue with the configuration we are showing you today.
If you are not familiar with the Frame Rating methodology, and how we had to change some things for mobile GPU testing, I would really encourage you to read this page of the previous mobility Frame Rating article for the scoop. The data presented below depends on that background knowledge!
Okay, you’ve been warned – on to the results.

Tagged: Overclocked, nvidia, just delivered, gtx 780, gtx 770, gtx 760, GTX 670 Mini, DirectCU II, DCII, asus
Returning home on Monday, I was greeted by several (slightly wet) boxes from Asus. Happily, the rainstorm that made these boxes a bit damp did not last long, and the wetness was only superficial. The contents were perfectly fine. I was pleased by this, but not particularly pleased with FedEx for leaving them in a spot where they got wet. All complaints aside, I was obviously ecstatic to get the boxes.
Quite the lineup. The new packaging is sharp looking and clearly defines the contents.
Inside these boxes are some of the latest and greatest video cards from Asus. Having just finished up a budget roundup, I had the bandwidth available to tackle a much more complex task. Asus sent four cards for our testing procedures, and I intend to go over them with a fine toothed comb.
The smallest of the bunch is the new GTX 670 DC Mini. Asus did some serious custom work to not only get the card as small as it is, but also to redesign the power delivery system so that the chip only requires a single 8 pin PCI-E power connection. Most GTX 670 boards require 2 x 6 pin connectors which would come out to be around 225 watts delivered, but a single 8 pin would give around 175 watts total. This is skirting the edge of the official draw for the GTX 670, but with the GK104 chip being as mature as it is, there is some extra leeway involved. The cooler is quite compact and apparently pretty quiet. This is aimed at the small form factor crowd who do not want/need a overly large card, but still require a lot of performance. While the GTX 700 series is now hitting the streets, there is still a market for this particular card. Oh, and it is also overclocked for good measure!
We see a nice progression from big to little. It is amazing how small the GTX 670 DC Mini is compared to the rest, and it will be quite interesting to see how it compares to the GTX 760 in testing.
The second card is the newly released GTX 760 DCII OC. This is again based on the tried and true GK104 chip, but has several units disabled. It has 1152 CUDA cores, but retains the same number of ROPS as the fully enabled chips. It also features the full 256 bit memory bus running at 6 Gbps. It has plenty of bandwidth to provide the card in most circumstances considering the amount of functional units enabled. The cooler is one of the new DirectCU II designs and is a nice upgrade in both functionality and looks from the previous DCII models. It is a smaller card than one would expect, but that comes from the need to simplify the card and not overbuild it like the higher priced 770 and 780 cards. As I have mentioned before, I really like the budget and midrange cards. This should be a really fascinating card to test.
The next card is a bit of an odd bird. The GTX 770 DCII OC is essentially a slightly higher clocked GTX 680 from yesteryear. One of the big changes is that this particular model foregoes the triple slot cooler of the previous generation and implements a dual slot cooler that is quite heavy and with a good fin density. It features six pin and eight pin power connections so it has some legs for overclocking. The back plate is there for stability and protection, and it gives the board a very nice, solid feel. Asus added two LEDs by the power connections which show if the card is receiving power or not. This is nice, as the fans on this card are very silent in most situations. Nobody wants to unplug a video card that is powered up. It retains the previous generation DCII styling, but the cooler performance is certainly nothing to sneeze at. It also is less expensive than the previous GTX 680, but is faster.
All of the cards sport dual DVI, DisplayPort, and HDMI outputs. Both DVI ports are dual-link, but only one is DVI-I which can also output a VGA signal with the proper adapter.
Finally we have the big daddy of the GTX 700 series. The 780 DCII OC is pretty much a monster card that exceeds every other offering out there, except the $1K GTX Titan. It is a slightly cut down chip as compared to the mighty Titan, but it still packs in 2304 CUDA cores. It retains the 384 bit memory bus and runs at a brisk 6 Gbps for a whopping 288.4 GB/sec of bandwidth. The core is overclocked to a base of 889 MHz and boosts up to 941 MHz. The cooler on this is massive. It features a brand new fan design for the front unit which apparently can really move the air and do so quietly. Oddly enough, this fan made its debut appearance on the aforementioned GTX 670 DC Mini. The PCB on the GTX 780 DCII OC is non-reference. It features a new power delivery system that should keep this board humming when overclocked. Asus has done their usual magic in pairing the design with high quality components which should ensure a long lifespan for this pretty expensive board.
I do like the protective plates on the backs of the bigger cards, but the rear portion of the two smaller cards are interesting as well. We will delve more into the "Direct Power" functionality in the full review.
I am already well into testing these units and hope to have the full roundup late next week. These are really neat cards and any consumer looking to buy a new one should certainly check out the review once it is complete.
Asus has gone past the "Superpipe" stage with the GTX 780. That is a 10 mm heatpipe we are seeing. All of the DCII series coolers are robust, and even the DC Mini can dissipate a lot of heat.

Tagged: windforce 450w, gtx 760, gigabyte, factory overclocked
Gigabyte is reportedly launching a new GTX 760 graphics card with 4GB of GDDR5 memory. It will be paired with the company’s WindForce 450W cooler and uses the same PCB as its Gigabyte GTX 770 sibling.
The upcoming Gigabyte GTX 760 4GB WindForce OC is model number GV-N760OC-4GD. As the name suggests, the card comes with a decent factory overclock on the GPU. The card uses NVIDIA’s GTX 760 GPU with 1,152 CUDA cores, 96 TMUs, and 32 ROPs within 6 SMX units. Gigabyte has overclocked the GPU to 1085 MHz base and 1150 MHz boost. For comparison, the reference GTX 760 is has a base clockspeed of 980 MHz and a boost clockspeed of 1033 MHz. Memory on the Gigabyte GTX 4GB WindForce OC remains the same as the stock design, at 6GHz, there is just more of it at 4GB total versus the stock 2GB of GDDR5.
The factory overclocked card features an eight-phase VRM and the company’s WindForce 3X 450W cooler. The dual slot, triple fan cooler has three 80mm fans cooling two aluminum fin stacks that connect to the copper baseplate via two 8mm and four 6mm heatpipes. It is rated to cool up to 450W TDPs. Because this factory overclocked graphics card is based on the same PCB Gigabyte used for its GTX 770, it requires a single 6-pin and a single 8-pin PCI-E power connector. This setup should provide ample power to push voltage and get higher overclocks, the specific GPU permitting.
There is no pricing or availability information yet, but expect it to be around $270 since its 2GB sibling has an MSRP of $260. Additional photos of the new graphics card can be found over at Tech Power Up.

Battle of the IGPs
Our long journey with Frame Rating, a new capture-based analysis tool to measure graphics performance of PCs and GPUs, began almost two years ago as a way to properly evaluate the real-world experiences for gamers. What started as a project attempting to learn about multi-GPU complications has really become a new standard in graphics evaluation and I truly believe it will play a crucial role going forward in GPU and game testing.
Today we use these Frame Rating methods and tools, which are elaborately detailed in our Frame Rating Dissected article, and apply them to a completely new market: notebooks. Even though Frame Rating was meant for high performance discrete desktop GPUs, the theory and science behind the entire process is completely applicable to notebook graphics and even on the integrated graphics solutions on Haswell processors and Richland APUs. It also is able to measure performance of discrete/integrated graphics combos from NVIDIA and AMD in a unique way that has already found some interesting results.
Battle of the IGPs
Even though neither side wants us to call it this, we are testing integrated graphics today. With the release of Intel’s Haswell processor (the Core i7/i5/i3 4000) the company has upgraded the graphics noticeably on several of their mobile and desktop products. In my first review of the Core i7-4770K, a desktop LGA1150 part, the integrated graphics now known as the HD 4600 were only slightly faster than the graphics of the previous generation Ivy Bridge and Sandy Bridge. Even though we had all the technical details of the HD 5000 and Iris / Iris Pro graphics options, no desktop parts actually utilize them so we had to wait for some more hardware to show up.
When Apple held a press conference and announced new MacBook Air machines that used Intel’s Haswell architecture, I knew I could count on Ken to go and pick one up for himself. Of course, before I let him start using it for his own purposes, I made him sit through a few agonizing days of benchmarking and testing in both Windows and Mac OS X environments. Ken has already posted a review of the MacBook Air 11-in model ‘from a Windows perspective’ and in that we teased that we had done quite a bit more evaluation of the graphics performance to be shown later. Now is later.
So the first combatant in our integrated graphics showdown with Frame Rating is the 11-in MacBook Air. A small, but powerful Ultrabook that sports more than 11 hours of battery life (in OS X at least) but also includes the new HD 5000 integrated graphics options. Along with that battery life though is the GT3 variation of the new Intel processor graphics that doubles the number of compute units as compared to the GT2. The GT2 is the architecture behind the HD 4600 graphics that sits with nearly all of the desktop processors, and many of the notebook versions, so I am very curious how this comparison is going to stand.

Tagged: R7730, msi, graphics card, GCN, 7730
If rumors hold true, consumers may be greeted with a new AMD Radeon graphics card today, in the form of a Graphics Core Next (GCN) based HD 7730. According to the leak by Videocardz, MSI will be launching a new card based on this budget GPU called the R7730-1GD5V1. It will use a shrouded fan and heatsink cooler with the company's propeller blade fan technology. Afterburner support and solid capacitors are also features of the MSI card that is rumored to use this new GPU chip. Video ouptuts include one DVI, one HDMI, and one DisplayPort connector.
The HD 7730 GPU itself is based on the same basic Cape Verde chip as the existing HD 7750 and HD 7770 GPUs. However, the HD 7730 has fewer stream processors. Specifically, the 7730 will use 384 stream processors clocked at 800 MHz. It will be paired with 1GB of GDDR5 memory on a 128-bit bus, with the memory clocked at 4.5 GHz. For comparison, the HD 7750 features 512 stream processors clocked at 800 MHz along with 1GB of GDDR5 at 4.5GHz.
This new chip will not be as fast as the similarly-clocked HD 7750, but it will also be cheaper and use less power as it is able to get all of its power from the PCI-E bus (no PCI-E power cable from the PSU required).
The MSI HD 7730 graphics card is rumored to launch sometime today for 70 Euros, or about $90 USD. (At least we will not have long to wait to see if the rumors are true!)

Tagged: radeon hd 7990, frame rating, amd, 7990
Editor's Update (Ryan): After the long holiday I finally got around to asking AMD for an official response to this rumor. AMD says simply:
"Plain and simple: AMD has not EOL'd the world's fastest graphics card, the AMD Radeon HD 7990."
Obviously the company is steadfast that the report from WCCFTech is incorrect so I eagerly await the new driver due by July 31st for improved frame pacing and multi-GPU performance!
WCCFTech caught wind, via Overclockers.Ru, of a Radeon HD 7990 cancellation rumor. The flagship card, codenamed after the Mediterranean island, "Malta", contains two Graphics Core Next (GCN) GPUs in Crossfire. Before the canonical AMD design, certain third-party add-in-board (AIB) partners created their own designs with the 7990 moniker with a pair of 7970 GPUs as its foundation. The first official 7990s launched in April 2013.
But, it did not have the best reception.
Never Settle, get it before it settles.
The two main issues regarding 7990 adoption are, according to WCCFTech, micro-stuttering with Crossfire setups and the better dollar value of paired 7970s. The 7990 comes in at the thousand dollar ($1000 USD) price point despite being, for all intents and purposes, nearly identical to a pair of separate 7970 cards. While the 7990 has access to a superior "Never Settle" bundle when compared to twin 7970s, with the addition of a Deux Ex: Human Revolution license, it would be difficult to consider that as an excuse for the $200-$300 USD price gap.
Cost aside, this would be a really odd time to cancel the 7990. The product was launched just a few months ago, despite similar price concerns, only to be allegedly killed right before the driver that makes it worth its weight? If true, either AMD decided to annul their "mistake", or we will get some interesting news when the frame pacing driver finally gets released.
While pure speculation, my immediate reflex would be that AMD had some problem during the development of their frame pacing driver. The initial results presented by Ryan showed a great improvement, but what about a pair of 7990 cards? The way in which they, allegedly, are killing off the 7990 would suggest something abrupt came up.
Hopefully, for AMD, that was not the case.
