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.

IMG_0141.JPG

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.

Just Delivered: The Latest Midrange to High End NVIDIA Graphics Cards from ASUS

Subject: Graphics Cards | July 10, 2013 - 01:48 PM |
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.

asus_jd_01.jpg

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!

asus_jd_02.jpg

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.

asus_jd_03.jpg

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.

asus_jd_04.jpg

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_jd_05.jpg

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.

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. 

 

mbair.JPG

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.

The GPU Midrange Gets a Kick

I like budget video cards.  They hold a soft spot in my heart.  I think the primary reason for this is that I too was once a poor college student and could not afford the really expensive cards.  Ok, so this was maybe a few more years ago than I like to admit.  Back when the Matrox Millennium was very expensive, I ended up getting the STB Lightspeed 128 instead.  Instead of the 12 MB Voodoo 2 I went for the 8 MB version.  I was never terribly fond of paying top dollar for a little extra performance.  I am still not fond of it either.

The sub-$200 range is a bit of a sweet spot that is very tightly packed with products.  These products typically perform in the range of a high end card from 3 years ago, yet still encompass the latest features of the top end products from their respective companies.  These products can be overclocked by end users to attain performance approaching cards in the $200 to $250 range.  Mind, there are some specific limitations to the amount of performance one can actually achieve with these cards.  Still, what a user actually gets is very fair when considering the price.

budg_01.jpg

Today I cover several flavors of cards from three different manufacturers that are based on the AMD HD 7790 and the NVIDIA GTX 650 Ti BOOST chips.  These range in price from $129 to $179.  The features on these cards are amazingly varied, and there are no “sticker edition” parts to be seen here.  Each card is unique in its design and the cooling strategies are also quite distinct.  Users should not expect to drive monitors above 1920x1200, much less triple monitors in Surround and Eyefinity.

Now let us quickly go over the respective chips that these cards are based on.

NVIDIA launches the GTX 760 @ $250; let the price wars begin again!

Subject: Graphics Cards | June 25, 2013 - 01:28 PM |
Tagged: geforce, GK104, gtx 760, nvidia, msi, MSI N760 TF 2GD5/OC

To start off with the good news, the GTX 760 is now available between $250 to $260 for the MSI model that [H]ard|OCP reviewed.  No paper launch this, nor another $400+ card for you to dream about but instead a solid performing card at a decent price.  Power is provide by an 8-pin and a 6-pin PCIe power connector, perhaps a little more than the card needs but perfect for overclockers who need the extra juice.  Performance wise the card trumps the GTX 660Ti and matches the GTX 670 and HD7950 boost in almost every test, for a good $50-75 less to pick up.  Even better news is that some certain sites testing Frame Rating and SLI performance saw great scaling in real performance. 

Read on to get the whole picture from [H]ard|OCP.

"Today NVIDIA is launching the GeForce GTX 760. The GeForce GTX 760 will be replacing a video card and offering what use to be high-end memory performance, at a mainstream price. We will evaluate a retail MSI N760 TF 2GD5/OC video card with comparisons to find out whether or not this is a true value."

Getting even more life from GK104

Have you guys heard about this new GPU from NVIDIA?  It’s called GK104 and it turns out that the damn thing is found yet another graphics card this year – the new GeForce GTX 760.  Yup, you read that right, what NVIDIA is saying is the last update to the GeForce lineup through Fall 2013 is going to be based on the same GK104 design that we have previously discussed in reviews of the GTX 680, GTX 670, GTX 660 Ti, GTX 690 and more recently, the GTX 770. This isn’t a bad thing though!  GK104 has done a fantastic job in every field and market segment that NVIDIA has tossed it into with solid performance and even better performance per watt than the competition.  It does mean however that talking up the architecture is kind of mind numbing at this point…

block.jpg

If you are curious about the Kepler graphics architecture and the GK104 in particular, I’m not going to stop you from going back and reading over my initial review of the GTX 680 from January of 2012.  The new GTX 760 takes the same GPU, adds a new and improved version of GPU Boost (the same we saw in the GTX 770) and lowers down the specifications a bit to enable NVIDIA to hit a new price point.  The GTX 760 will be replacing the GTX 660 Ti – that card will be falling into the ether but the GTX 660 will remain, as will everything below it including the GTX 650 Ti Boost, 650 Ti and plain old 650.  The GTX 670 went the way of the dodo with the release of the GTX 770.

01.jpg

Even though the GTX 690 isn't on this list, NVIDIA says it isn't EOL

As for the GeForce GTX 760 it will ship with 1152 CUDA cores running at a base clock of 980 MHz and a typical boost clock of 1033 MHz.  The memory speed remains at 6.0 GHz on a 256-bit memory bus and you can expect to find both 2GB and 4GB frame buffer options from retail partners upon launch.  The 1152 CUDA cores are broken up over 6 SMX units and that means you’ll see some parts with 3 GPCs and others with 4 – NVIDIA claims any performance delta between them will be negligible.

Frame Rating: AMD plans driver release to address frame pacing for July 31st

Subject: Graphics Cards | June 20, 2013 - 04:05 PM |
Tagged: radeon, nvidia, geforce, frame rating, fcat, crossfire, amd

Well, the date has been set.  AMD publicly stated on its @AMDRadeon Twitter account that a new version the prototype driver we originally previewed with the release of the Radeon HD 7990 in April will be released to the public on July 31st.  For a problem that many in the industry didn't think existed.  

 

 

Since that April release AMD has been very quiet about its driver changes and actually has refused to send me updated prototypes over the spring.  Either they have it figured out or they are worried they haven't - but it looks like we'll find out at the end of next month and I feel pretty confident that the team will be able to address the issues we brought to light.

For those of you that might have missed the discussion, our series of Frame Rating stories will tell you all about the issues with frame pacing and stutter in regards to AMD's CrossFire multi-GPU technology. 

AMD gave the media a prototype driver in April to test with the Radeon HD 7990, a card that depends on CrossFire to work correctly, and the improvements were pretty drastic.

BF3_2560x1440_PLOT_0.png

So what can we expect on July 31st?  A driver that will give users the option to disable or enable the frame pacing technology they are developing - though I am still of the mindset that disabling is never advantageous.  More to come in the next 30 days!
