GeForce GTS 450 1GB vs Radeon HD 4870 512MB
Intro
The GeForce GTS 450 1GB has core speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4870 512MB, which features GPU clock speed of 750 MHz, and 512 MB of GDDR5 memory running at 900 MHz through a 256-bit bus. It also features 800(160x5) Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.

2 Responses to “GeForce GTS 450 1GB vs Radeon HD 4870 512MB”Well, I'm happy. I just bought the 4870, and it's nice to know I'm finally running faster than my friend Jessie.
Doesn't make sense, though. He can run Crysis 2 on Extreme at around 30-40 fps, whereas I run it at around 25-35 fps.
I'd say it's our difference in CPU power.
Mine: Phenom II x3 720 2.8ghz
His: Phenom II x4 830 2.8ghz.
Or maybe it's because the 4870 is not a DX11 card.
What do you think?
CPU. OC that beast to 3.2GHz, and you may get his FPS.
It's definitely not that it isn't a DX11 Card, Crysis 2 isn't a DX11 game.
