Regardless of how hard we tired, we weren’t able to find performance of AMD CPUs while using 4K by 4K matrix.Īs you can see for yourself, Larrabee is finally starting to produce some positive results. If you’re wondering where products such as Intel Harpertown-based Core 2 Quad or Nehalem-based Core i7 stand, the answer is quite simple – i7 XE 975 at 3.33 GHz will give you 101 GFLOPS, while Core 2 Extreme QX9770 at 3.2 GHz gives out 91 GFLOPS.
The same thing goes for nVidia’s long-delayed NV100-based family of products.īut as of SC09, the top five performing products for SGEMM 4K x 4K are as follows :ġ. We don’t have information about SGEMM performance of Evergreen GPUs but as soon as we learn the numbers – we’ll let you know. Long story short, the real-world SGEMM performance of AMD’s FireStream 9270 board is 300 GFLOPS, weaker than GT200. Thus, the Radeon 4800 family comes with 160 cores comparable to nVidia 30 clusters with 8 fully-featured cores i.e. As we disclosed on numerous occasions, AMD introduced the 1Fat+4Thin concept with the ATI Radeon 2900XT, pulling in a Core cluster consists out of one unit for transcendental operations and four units for Multiply-Add/Add/Integer-Add/Dot operations. But those efforts cannot accommodate for architectural limitations. When it comes to GPGPU world, AMD ditched everything else to focus on OpenCL development and the results will come in 2010. AMD’s architecture is very strong in theoretical performance and in real-world gaming. One might mention AMD GPU line-up being more efficient than nVidia one, but unfortunately the situation is rather complex due to interesting state of AMD GPGPU developments. Thus, Larrabee today comes at 2.7x math performance of GT200 chip. Now, we can debate the numbers all we want, but the fact of the matter is that nVidia Tesla C1060 delivers only 370 GFLOPS in an identical SGEMM 4Kx4K calculation. A couple of minutes before the end of the keynote, Justin added the infamous “And one more thing…” Initial overclocked performance was 913 GFLOPS, moved slowly past 919 GLOPS, bounced up to 997 GFLOPS and ultimately passed the 1TFLOPS barrier with 1006 GFLOPS. The keynote continued while the engineers scrambled at the back to try to beat the 1TFLOPS barrier. Of course, there is a “but” coming – unlike theoretical numbers that are usually disclosed by ATI and nVidia – this was an actual SGEMM benchmark calculation used in the HPC community. While looking at the numbers alone, one might think that these scores are below the level of ATI Radeon 4850 and nVidia GeForce GTX 280/GTX 285. During Justin Rattner’s keynote, Intel demonstrated the performance of LRB as it stands today.Īt SGEMM Performance test, Intel achieved 417 GFLOPS using half the cores on the prototype card, and reached 825 GFLOPS by enabling all the cores. Back in 2006, when we first got the first details about Larrabee, the performance goal 16 cores, 2.0 GHz clock, 150W TDP”. Hovering over the value, you can get individual results.During the recently held SC09 conference in Portland, Oregon – Intel finally managed to reach its original performance goal for Larrabee. The value depicts the average frame rate. The interpolation in the same category is not possible. Uncertain – How graphics cards operate in the game is being examined for the time being. Uncertain – The graphics card testing has revealed a slower card might ensure a high and stable frame rate. As per interpolation of the similar graphics cards showing low frame rates, the game is possible to lag. May Run Fluently – How graphics cards operate in the game is being examined for the time being. As per interpolation of the similar graphics cards showing low frame rates, the game is possible to lag.įluent – In considering all graphics benchmarks, the game speed is likely to be 25 fps or more.įluent – In considering all graphics benchmarks, the game speed is likely to be 35 fps or more.įluent – In considering all graphics benchmarks, the game speed is likely to be 58 fps or more.
