Compare any two graphics cards:
GeForce GTX 650 vs Radeon R9 270
IntroThe GeForce GTX 650 has a core clock speed of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 32 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon R9 270, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a speed of 1400 MHz on this model. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 270 is 124% quicker than the GeForce GTX 650 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon R9 270 is much (more or less 113%) better at AF than the GeForce GTX 650. (explain)
Pixel RateThe Radeon R9 270 is a lot (more or less 70%) better at anti-aliasing than the GeForce GTX 650, and should be capable of handling higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, 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 most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

2 Responses to “GeForce GTX 650 vs Radeon R9 270”I think AMD wins on this test and AMD based technology is better because of AMD FX proccesor serias based for this type of APU or Gpu i don't know.
Acho que será uma boa troca pois a que estou comprando é um modelo de referencia [Obs.Sem intervenções de outros Frabricantes]
