Compare any two graphics cards:
GeForce GTX 650 vs Radeon HD 5870
IntroThe GeForce GTX 650 features a GPU core speed of 1058 MHz, and the 1024 MB of GDDR5 memory is set to run at 1250 MHz through a 128-bit bus. It also features 384 Stream Processors, 32 TAUs, and 16 ROPs.Compare all that to the Radeon HD 5870, which comes with a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 1600(320x5) SPUs, 80 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5870, in theory, should be quite a bit faster than the GeForce GTX 650 in general. (explain)
Texel RateThe Radeon HD 5870 is quite a bit (about 101%) faster with regards to AF than the GeForce GTX 650. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5870 is a better choice, and very much so. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

2 Responses to “GeForce GTX 650 vs Radeon HD 5870”Why is your GTX 650 listed as having 2048mb GDDR5 rams when it only has 1024? that makes no sense to me and this is the only place i've found that suggesd this.
You are correct, slight oversight, will be fixed.
There actually are 2GB versions available.
