GeForce GTX 560 Ti vs Radeon HD 5770

Intro

The GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 memory works at a speed of 1002 MHz on this particular model. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.

Compare all that to the Radeon HD 5770, which comes with a clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.

Radeon HD 5770 76800 MB/sec
Difference: 51456 (67%)

Texel Rate

The GeForce GTX 560 Ti should be a lot (approximately 55%) better at anisotropic filtering than the Radeon HD 5770. (explain)

GeForce GTX 560 Ti 52608 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 18608 (55%)

Pixel Rate

The GeForce GTX 560 Ti should be much (approximately 93%) more effective at full screen anti-aliasing than the Radeon HD 5770, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 12704 (93%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at 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 video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure 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 output 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 reach the maximum fill rate.

[...] Third argument is upgradability. Go google “iMac”. Look at it. It’s a giant white square pancake with a keyboard and a mouse with one button connected to it. It’s like a laptop: not very powerful and annoying to upgrade. Notice I said “annoying” and not impossible. Upgrading RAM is just finding compatible RAM and slotting it in which I think means the Apple store or Apple suppliers only. Not much room for fans there either. I went to the electronics store here the other day and touched the back of the screen of an iMac that had been on all day… it literally burnt my fingers. You could look into the Mac Pro, the tower Mac but they range in price from $2.5k- $5k (AU$3k-$6k). Here I’d like to point out that for AU$3400 (comparing to the AU$6k Mac Pro), you can get the NRG Avalanche that has half the cores (6 cores @ 3.9Ghz that have been overclocked to 4.5Ghz), twice as much hard drive space (plus a 120GB SSD), 10GB more RAM, and a slightly more powerful graphics card.
