GeForce GTX 560 vs Radeon HD 6850

Intro

The GeForce GTX 560 comes with a core clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit bus, and uses a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Compare all that to the Radeon HD 6850, which has a clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 960 SPUs, 48 TAUs, and 32 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 will be 0% faster than the Radeon HD 6850 overall, due to its higher bandwidth. (explain)

GeForce GTX 560 128128 MB/sec
Radeon HD 6850 128000 MB/sec
Difference: 128 (0%)

Texel Rate

The GeForce GTX 560 is quite a bit (more or less 22%) faster with regards to anisotropic filtering than the Radeon HD 6850. (explain)

GeForce GTX 560 45360 Mtexels/sec
Radeon HD 6850 37200 Mtexels/sec
Difference: 8160 (22%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, but not by far. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon HD 6850 24800 Mpixels/sec
Difference: 1120 (5%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past 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 type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

Radeon is much..much better..dx

Bruder95 says:

rasta dumm? oder so mann siehts eindeutig das die 560 besser ist TAUSEND MAL BESSER bei alles

maiky says:

Bruder95 auch dumm? Dafür das die Radeon nur die hälfte kostet, ist sie Leistungstechnisch fast genau so gut. die paar texel und pixel machen minimal etwas aus. bei Spielen wie BF3 wird man den Unterschied etwas merken.

HOW THE f**K U CAME UP WITH THE IDEA THAT RANDON 6850 IS BETTER THEN 560GTX CAN4T U SEE THE BOARD

6850 core speed is infact higher than 775 usually depending on the brand is 790-820

On even modest o'clocks with the HD 6850, +11% core & +12.5% memory (860/1125), the 6850 posts: pixel fill @ 27.5GP/s, texture fill @ 41.3GT/s and mem' b/w @ 144GB/s. Bear in mind, i've brought the clocks down from the core:950/mem:1175, that i've been using for 3D gaming, just to demonstrate the incrdible o'clock potential the 6850 has. Obviously, YEMV. So it's a no-brainer .. if you want a very good card - out of the box, the GTX 560 is it. If you want an excellent o'clock candidate that has huge potential beyond its stock/factory settings? Than you probably wanna go with the HD 6850.

@SAM ... i think you and rilder should "hook up" ... you seem to think *alot* alike.
