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

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to 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.
