GeForce GTX 650 Ti vs Radeon HD 7850

Intro

The GeForce GTX 650 Ti uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this model. It features 768 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare all of that to the Radeon HD 7850, which has GPU clock speed of 860 MHz, and 2048 MB of GDDR5 RAM running at 1200 MHz through a 256-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.

I would like to see Game bench results. The 650Ti is one of those cards that is overlooked. Many do not realize just how good a card it is. I had a 5870 in my i5 that the fan went out on. When I purchased the 650Ti (91$ Bucks)I thought it would be a little less or the same in performance as the 5870. But it does so much better than the 5870 on my i5. I would say it will beat the 7850 too.
