NVIDIA GeForce GTX 460 1GB & GTX 460 768MB Launch Review
◆GeForce GTX 460 Structure Analysis
GF104 structure
GF104 structure
The GF104 is manufactured on using TSMC’s advanced 40nm process, and features 1.95 billion transistors(While the GF100 features over 3 billion); In the powering configuration the GeForce GTX 460, the chip sports 2 graphics processing clusters, 7 streaming multiprocessors, 336 CUDA cores, 56 texture units, and 24 (768MB card) or 32 (1GB card) ROPs. What you’ll also notice is that the GF104 is actually comprised of 8 streaming multiprocessing units, each of the streaming multiprocessors in the GF104 GPU features 48 CUDA cores, 8 texture units, various registers and cache, and its own PolyMorph engine. You can see each functional block outlined in the diagram above.
GF104 specs as follows:
－Up to 256 CUDA Cores
－8 Geometry Units
－2 Raster Units
－56 Texture Units
－32 ROP Units
－256-bit GDDR5
－DirectX-11 API Support
The main changes to the SM come with the number of CUDA cores as well as the number of texture units each houses. Instead of the usual 32 cores per SM, the GF104 uses a structure which allows for 48 cores along with 16 load / store units and 8 Special Function Units. This in and of itself is quite an eye opener but the real differences are with the number of texture units each Streaming Multiprocessor houses. The GF100 cards have four texture units per SM while the NVIDIA equipped the GF104 with eight TMUs per SM. This can and will lead to a massive increase in texture performance which will benefit older DX10 and DX9 games.
Comparision of products specs
There are two different versions of the GTX 460. One has a 1024MB of GDDR5 as well as 256-bit memory interface, and the other has a 768MB of GDDR5 as well as 192-bit memory interface. Based on Fermi’s third-generation Streaming Multiprocessor architecture, the GeForce GTX 460 boasts 336 CUDA cores, core/Shader/memory clocked at 675/1350/3600MHz.
GTX 460 768MB with the maximum TDP of 155W sells for $192, and 1GB with the maximum TDP of 160W sells for $221.
What we need to mention is that GeForce GTX 460 supports Dolby True HD and DTS-HD Master Audio.

Plagiat article. This is a copy of guru3d.com “GeForce GTX 460 review (roundup)” article: http://www.guru3d.com/article/geforce-gtx-460-review/30.
What a lame reviewer!
And dont remove my comment asshole!
“As a result, we see a lot of board partners offering many brand based SKU’s with several faster clocked / levels. So when we look at the reference baseline we are satisfied with what we have seen. It really is nice performance at that price level, and it will certainly hit a sweet-spot. Obviously we recommend the 1GB version over the 768MB version, not so much for the extra memory but for the 8 ROP partitions the 1GB version has extra. A lot of performance can be found there making it the more mature product. But do not underestimate the 768MB models though as they offer very decent bang for buck. Especially the faster clocked 768MB, it surprised me big-time.”

Aw, this was a really nice post. In concept I wish to put in writing like this additionally – taking time and actual effort to make an excellent article… but what can I say… I procrastinate alot and on no account seem to get one thing done.

If you really want you can look the other way and not talk about it.but you talked.thanls.Don’t give up your morals for anything. This will lead to a sad and unfulfilling life.
