AMD RADEON R7 265 DRIVERS
(on Linux: 1.1 (no Image support) with Mesa 3D, 2.0 with AMD drivers or AMD ROCm) The following table shows features of AMD/ ATI's GPUsĤ.5 (on Linux: 4.5 (Mesa 3D 21.0)) ġ.2 (on Linux: 1.1 (no Image support) with Mesa 3D) Vega - UVD 7.0, VCE 4.0 and VCN 1.0 only at AMD Raven Ridge.Volcanic Islands - UVD 5.0, 6.0, VCE 3.0.Northern Islands - UVD 3 (HD 67xx UVD 2.2).R300 - Video Immersion II + Video Shader.The following tables are for reference use only, and do not reflect actual performance. API support – Rendering and computing APIs supported by the GPU and driver.ĭue to conventions changing over time, some numerical definitions such as core config, core clock, performance and memory should not be compared one-to-one across generations.Bus interface – Bus by which the graphics processor is attached to the system (typically an expansion slot, such as PCI, AGP, or PCIe).TBP (Typical board power) – Typical power drawn by the total board, including power for the GPU chip and peripheral equipment, such as Voltage regulator module, memory, fans, etc., measured in Watt.TDP ( Thermal design power) – Maximum amount of heat generated by the GPU chip, measured in Watt.Bandwidth – Maximum theoretical memory bandwidth based on bus type and width.Clock – The reference memory clock frequency.Bus width – Maximum bit width of the memory bus utilized.Bus type – Type of memory bus utilized.Vertex operations - The amount of geometry operations that can be processed on the vertex shaders in one second (only applies to Direct3D 9.0c and older GPUs).Shader operations - How many operations the pixel shaders (or unified shaders in Direct3D 10 and newer GPUs) can perform.Texture - The rate at which textures can be mapped by the texture mapping units onto a polygon mesh.Pixel - The rate at which pixels can be rendered by the raster operators to a display.Core clock – The reference base and boost (if available) core clock frequency.Core config – The layout of the graphics pipeline, in terms of functional units.Die Size – Physical surface area of the die.Transistors – Number of transistors on the die.Average feature size of components of the GPU. Architecture – The microarchitecture used by the GPU.Codename – The internal engineering codename for the GPU.

The headers in the table listed below describe the following:
However, we've managed to overclock the Curaçao/Pitcairn GPU higher without stability issues, so 925 MHz seems reasonable.īecause the GPU is a first-gen implementation of Graphics Core Next, the Radeon R7 265 doesn't offer any of the features introduced alongside AMD's R7 260X and R9 290/290X cards (like TrueAudio). We're not sure this will be the case for all Radeon R7 265s.
It doesn't throttle back, even after running FurMark's stability test for just under an hour. However, the R7 265 we're testing is provided by Sapphire and includes the company's Dual-X thermal solution. Claims of 1000 and 947 MHz, respectively, turned out to be much lower when the Hawaii-based cards got hot. But as you increase resolution and enable anti-aliasing, the 265's bandwidth should prove more valuable.ĭid you notice that AMD prefaces the R7 265's clock rate with an "up to"? This really bit the company on the butt with its first batch of R9 290X and 290 boards sporting reference coolers. In shader-limited situations, the 260X should hang tight. Where the 260X compromises performance is on the back-end, which features half as many ROP partitions and a 128-bit memory bus. Rated for up to 1.89 TFLOPS of FP32 compute performance at its peak clock rate, the Radeon R7 265 falls a bit shy of the R7 260X, which hosts fewer active shaders, but runs at a more aggressive 1.1 GHz GPU frequency. With all of that said, you can see AMD's Radeon R7 265 is an overclocked Radeon HD 7850 that employs a 900 MHz base clock rate, a 925 MHz PowerTune with Boost accelerated state, and a 1400 MHz memory frequency.
