Third, it's cheaper, with a base price of $139 for a 2GB card, as opposed to $149 for the 1GB card. Second, it's clocked higherthe HD 7790 was clocked at 1GHz core clock and 1,500MHz memory, while the R7 260X clocks in at 1,100 MHz core and 1,625MHz for a gain of 10 percent and 8 percent, respectively. First, it doubles its onboard RAM buffer, up to 2GB, from 1GB. The R7 260X improves on the Asus HD 7790 in three ways. The graphics card features two DVI ports, an HDMI port, and a DisplayPort and can drive up to three monitors off one card.
Like the Asus HD 7790, the R7 260X ($288.99 at Amazon) (Opens in a new window) is based on the company's Bonaire GPU, with 896 stream processors, a 128-bit path to main memory, 56 texture mapping units, and 16 render outputs. The AMD Radeon R7 260X ($139 list), a refresh of the Asus Direct CU II Radeon HD 7790 that we reviewed last year, is the company's main strike against Nvidia's lock on the budget graphics card market.

ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. It is measured in millions of texels processed per second. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. It especially helps with AA, HDR and higher screen resolutions. The higher the card's memory bandwidth, the better the card will be in general. If it uses DDR type memory, it should be multiplied by 2 again. It's calculated by multiplying the card's bus width by the speed of its memory. Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second.
