Hoy se desveló, gracias al fin del NDA, de las especificaciones finales del próximo GPU de Nvidia, se han publcado varios previews, en algunos se han publicado benchs colocando supuestos rendimientos del HD5870 para comparar aprox. cuales serán las diferencias.
Aquí les dejo toda la información recopilada:
- Benchmark Reviews
- Tom's Hardware
- Based on the Fermi architecture.
- "GF" indicates that the chip is a graphics solution based on the Fermi architecture.
- "100" denotes that this is the high end part of the "GF" family of GPUs.
- Utilizes six 64-bit GDDR5 memory controllers (384-bit total) to facilitate high bandwidth access to the framebuffer.
- Implements hardware accelerated DirectX 11 features including tessellation and DirectCompute.
- Supports next-generation effects such as ray-tracing, order-independent transparency, and fluid simulations.
- Enhances the geometric realism of characters and objects in games.
- Contains twice as many CUDA (Compute Unified Device Architecture) cores (512) over the previous architecture.
- The number of Render Output Units (ROP) per ROP partition has doubled over the previous architecture.
- Improvement in fillrate enables multiple displays to be driven.
- Improved ROP compression techniques lessen the performance hit of 8x multisampling antialiasing.
- Supports 32x coverage sampling antialiasing (CSAA) - final pixel color is determined using 8 multisamples and 24 coverage samples.
- CSAA was enhanced to support alpha-to-coverage on all samples, enabling higher quality rendering of foliage and transparent textures.
- Transparent objects can be rendered without presorting (order independent transparency) enabling developers to create levels with complex glass environments.
- On-chip L1 (64KB) and L2 (768KB) caches enable high-bandwidth transfer of primitive attributes between the graphics processor and the tessellation unit and between different graphics processors.
- The GigaThread engines reduces context switch time to about 20 microseconds making it possible to execute multiple compute and physics kernels for each frame.
- Contains an entirely new distributed geometry processing architecture that is implemented using multiple "PolyMorph" engines.
- Parallel geometry processing is possibly the single most important GF100 architectural improvement. The ability to deliver setup rates exceeding one primitive per clock while maintaining correct rendering order is a significant technical achievement never before done in a GPU.
- Information concerning price, clock speed, power usage and cooling were not provided
As you look at the charts below, you will notice that we added in “simulated” HD 5870 1GB results and there is a story behind this. NVIDIA was very forward with us and revealed the specifications of the test system they were running: a stock Intel i7 960, 6GB of 1600Mhz memory and an ASUS Rampage II Extreme motherboard running Windows 7. While we weren’t able to copy the exact same system, we did our best to replicate it by using the exact same CPU and OS while estimating the memory latencies and using a Gigabyte X58-UD5 motherboard. The result? Our stock GTX 285 performed within 2% of the results NVIDIA showed us so we are confident in the accuracy of our results.
Far Cry 2 DX10
While Far Cry 2 was released some time ago, it is still considered an extremely demanding game, especially at the Ultra High DX10 settings NVIDIA was using. They used the Ranch Small built-in timedemo which does tend to give a good approximation of the performance within the game itself.
1920 x 1200
The first indications seem to be that NVIDIA is definitely on the right track with the GF100 since it performs far above and beyond the older GTX 285. When you look at it in comparison to the current single GPU champ –the HD 5870 1GB – there just isn’t any competition at all and we are positive that even a highly overclocked HD 5870 won’t come anywhere near the GF100 we were shown.
Dark Void is an upcoming shooter which not only looks great but also takes advantage of some pretty wild PhysX effects. While we will be taking a closer look at this game and its performance at a later date, NVIDIA wanted to show it off in front of journalists prior to its release. For the results you see below, NVIDIA used the built-in benchmark that makes heavy use of in-game physics and the engine’s long draw distances.
This is one test where the GPU compute roots of the GF100 can really come into play by efficiently processing PhysX and rendering the scene at the same time. Performance is once again far beyond anything the GTX 285 can accomplish which should make things interesting come release.
