Alongside the Radeon R9 280X and R9 270X, AMD launched its entry-level Radeon R7 260X graphics card fit for visually-intensive desktops with some mild gaming thrown into the mix. The specifications of the R9 280X and R9 270X may dwarf those of the R7 260X, yet it deserves to be taken seriously from an academic standpoint. The graphics core inside the SoC that drives the Microsoft Xbox One entertainment system isn't all that different from the Radeon R7 260X, at least on paper.
The R7 260X is built around AMD's Bonaire silicon, which we have seen on the company's HD 7790 before. Unlike the HD 7790, it comes with 2 GB of memory and higher clock speeds. Its GPU core is clocked at 1100 MHz (compared to the 1000 MHz on the HD 7790) and memory runs at a scorching 1625 MHz (6.50 GT/s effective), which yields over 100 GB/s of memory bandwidth on even this relatively narrow, 128-bit wide memory bus. The bandwidth is then comparable to what GDDR5-enabled GPUs with 256-bit wide interfaces managed before the 4 GT/s GDDR5 era. The other big difference is in its memory amount: it is now at 2 GB as opposed to the 1 GB on the HD 7790. Based on the 28 nm "Bonaire" silicon, the Radeon R7 260X features 896 stream processors based on the Graphics CoreNext architecture, 56 texture memory units (TMUs), and 16 raster operations units (ROPs).
Today, we are reviewing the HIS Radeon R7 260X iPower IceQ X² using the same clocks and specs as the reference design, though it comes with an improved cooler. The HIS R7 260X iPower IceQ X² is currently available online for $150, which is $10 more than the reference design.
