GeForce GTX 560 Ti vs Radeon HD 6850

Intro

The GeForce GTX 560 Ti has a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 6850, which comes with a clock frequency of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 256-bit bus, and makes use of a 40 nm design. It features 960 SPUs, 48 Texture Address Units, and 32 ROPs.

Texel Rate

The GeForce GTX 560 Ti will be much (more or less 41%) faster with regards to texture filtering than the Radeon HD 6850. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
Radeon HD 6850 37200 Mtexels/sec
Difference: 15408 (41%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 Ti is a better choice, though not by far. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
Radeon HD 6850 24800 Mpixels/sec
Difference: 1504 (6%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 bandwidth is, the lower the potential to get to the max fill rate.

Hi man! this pages is excelent!, but I have a daubt about texel rate and Pixel rate...
How do you calculate these values? The Official NVidia page has diferent values about them.
Thx!

this is the shittiest page ever
blindly copied numbers, no real comparison data
useless waste of bandwidth

satan's just mad he gave me a blowjob and i didn't return the favor.

Both satan and Jesus are mad cuz they aren't real.

Athiest doesn't beleive in being mad, or anything else for that matter, so he's just there, wasting space.

But can we really know for sure?
TheTruthWhether you Like it or not says:
You cant ask someone to prove a negative, it doesnt work that way, for you to ask someone to prove something means you you have to prove it right first, otherwise your statement is botched.

Its really hard for anyone to disprove anything that hasnt been proven right yet, just as much as Id like you I cant prove that the easter bunny isnt real, or that the boggey man hiding in your closet isnt real.

All in all you cant ask someone "how do you know.. prove it" because the problem with that is that you havent proven your stance as correct yet, that means you cant ask someone to disprove you, when you have not proven to be correct in the first place.

Have a nice day,

Well the GTX 560 TI still costs around $220 while the HD 6850 is around $150. I personaly own a HD 6850 and I have no issues with it whatsoever and with the fact that it takes 43 less watts then the 560TI and costs $70 bucks cheaper I can afford to go crossfire with 2 HD 6850 for $300 bucks and 254 watts. Which would certaintly blow away the 560TI. If you went SLI with the 560 TI thats 340 watts and $440 bucks. it would most certanintly require you to buy a new psu 700 watts and up. Which I would say your safe around 550 watt psu with the hd 6850 in cf.

My own experience shows the Gigabyte HD 6850 Windforce has great overclocking potential, while operating at relatively low temps [centigrade](37 low load, 56 high load) throughout a typical session. I'm using Sapphire TRIXX (don't like, nor use, EVGA Precision X or CCC Overdrive) for my overclocking as it allows great control over: voltages, core & mem' clocks and also fan speeds. Last i looked, i had (stable):- Core: 835, Mem: 1110 & voltage at spec'. The GPU-Z readouts are:- Pixel Fill: 26.7GP/sec, Texture Fill: 40.1GT/sec, and Mem. Bandwidth: 142.1GB/sec. Now, on those figures alone, it puts the 6850 ahead on both Mem' bandwidth & Pixel Fill. That, and the fact the card is: (1) cheaper than the GTX-560Ti, (2) running at far lower TDP power consumption ($aving the owner $$$ in lower power bills), makes it a far better buying prospect overall than the GTX-560Ti. Granted they're both old/aging cards now, but it doesn't take a rocket scientist to see why anyone choosing between these two cards might sway in favor of the Red Team (imho of course). ;)
LarsV12 says:
UPDATE: After further voltage tweaking using Sapphire TRIXX, have the HD 6850 @ 1.231V. The overclocks sit at: core: 950, mem: 1175. At 950/1175, pixel fill: 30.4GP/s, Texture fill: 45.6GT/s, and Mem. Bandwidth: 150.4GB/sec .. i think on that type of huge o'cing headroom, the 6850 has to win, hands down.

I have the MSI AMD Radeon 6850 OC-Power-Edition and is very fast. Very good G-Card !!!
