Geforce GTX 760 vs Radeon R9 270

Intro

The Geforce GTX 760 comes with core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon R9 270, which comes with a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also features 1280 Stream Processors, 80 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.

Wow... price-to-performance on the Nvidia card is absolutely pathetic.

Guess you're paying for the brand.

rodrigues says:

nvidia no more. It Dosn't worth the difference of prices.

john says:

270 card performs the same and there is no real noticeable differnce on a 24inch 1080p 120 ghz screen-

price i go with r9 and its dx12 compatible

Ruru says:

The cards costs the same right now and Nvidia is the better choice.

Douglas says:

The same fot u in brazil the cust is like $50,00 difference r9 270 for gtx 760
