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.

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.

AMD may discontinue Radeon HD 7990

Subject: General Tech, Graphics Cards | July 4, 2013 - 06:02 PM |
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!

END UPDATE

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.

amd7990.jpg

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.

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

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.

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!

PCPer Live! Frame Rating and FCAT - Your Questions Answered!

Subject: Editorial, Graphics Cards | May 8, 2013 - 11:37 PM |
Tagged: video, nvidia, live, frame rating, fcat

Update: Did you miss the live stream?  Watch the on-demand replay below and learn all about the Frame Rating system, FCAT, input latency and more!!

I know, based solely on the amount of traffic and forum discussion, that our readers have really adopted and accepted our Frame Rating graphics testing methodology.  Based on direct capture of GPU output via an external system and a high end capture card, our new systems have helped users see GPU performance a in more "real-world" light that previous benchmarks would not allow.

I also know that there are lots of questions about the process, the technology and the results we have shown.  In order to try and address these questions and to facilitate new ideas from the community, we are hosting a PC Perspective Live Stream on Thursday afternoon.

Joining me will be NVIDIA's Tom Petersen, a favorite of the community, to talk about NVIDIA's stance on FCAT and Frame Rating, as well as just talk about the science of animation and input. 

fr-2.png

The primary part of this live stream will be about education - not about bashing one particular product line or talking up another.  And part of that education is your ability to interact with us live, ask questions and give feedback.  During the stream we'll be monitoring the chat room embedded on http://pcper.com/live and I'll be watching my Twitter feed for questions from the audience.  The easiest way to get your question addressed though will be to leave a comment or inquiry here in this post below.  It doesn't require registration and this will allow us to think about the questions before hand, giving it a better chance of being answered during the stream.

Our 4K Testing Methods

You may have recently seen a story and video on PC Perspective about a new TV that made its way into the office.  Of particular interest is the fact that the SEIKI SE50UY04 50-in TV is a 4K television; it has a native resolution of 3840x2160.  For those that are unfamiliar with the new upcoming TV and display standards, 3840x2160 is exactly four times the resolution of current 1080p TVs and displays.  Oh, and this TV only cost us $1300.

seiki5.jpg

In that short preview we validated that both NVIDIA and AMD current generation graphics cards support output to this TV at 3840x2160 using an HDMI cable.  You might be surprised to find that HDMI 1.4 can support 4K resolutions, but it can do so only at 30 Hz (60 Hz 4K TVs won't be available until 2014 most likely), half the refresh rate of most TVs and monitors at 60 Hz.  That doesn't mean we are limited to 30 FPS of performance though, far from it.  As you'll see in our testing on the coming pages we were able to push out much higher frame rates using some very high end graphics solutions.

I should point out that I am not a TV reviewer and I don't claim to be one, so I'll leave the technical merits of the monitor itself to others.  Instead I will only report on my experiences with it while using Windows and playing games - it's pretty freaking awesome.  The only downside I have found in my time with the TV as a gaming monitor thus far is with the 30 Hz refresh rate and Vsync disabled situations.  Because you are seeing fewer screen refreshes over the same amount of time than you would with a 60 Hz panel, all else being equal, you are getting twice as many "frames" of the game being pushed to the monitor each refresh cycle.  This means that the horizontal tearing associated with Vsync will likely be more apparent than it would otherwise.

I would likely recommend enabling Vsync for a tear-free experience on this TV once you are happy with performance levels, but obviously for our testing we wanted to keep it off to gauge performance of these graphics cards.
