GeForce GTX 560 Ti vs Radeon HD 4870 1GB
Intro
The GeForce GTX 560 Ti comes with a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 memory runs at 1002 MHz through a 256-bit bus. It also is comprised of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.Compare all of that to the Radeon HD 4870 1GB, which has core speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

2 Responses to “GeForce GTX 560 Ti vs Radeon HD 4870 1GB”Is better Gtx 560 Ti , HD 6950 or HD 4870 X2?? Can you help me please?
I got a HD 6950 2GB, but it looks like the 560Ti isn't far behind. The 4870 X2 should be a reasonable amount faster, but I don't have any actual benchmarks to back that up. It uses a LOT more power though. Personally I wouldn't go for a dual GPU card, the extra power usage and hassle isn't worth it to me. So it's between the 560Ti and the 6950... well, you know which one I got, but it looks like the 560 is a little bit faster in certain games and also uses less power.
