GeForce GTX 560 Ti vs Radeon HD 4870 1GB
Intro
The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 822 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this specific model. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.Compare that to the Radeon HD 4870 1GB, which has a core clock frequency of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also features a 256-bit memory bus, and makes use of a 55 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max 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.
