The 28 nm AMD Radeon R9 M265X is an mid-range notebook graphics card based on the GCN (Graphics Core Next) architecture. It was introduced in Spring of 2014 and supports up to DirectX 12 (FL 11_1). The underlying "Cape Verde" GPU features 640 unified shaders, a core clock of 625 MHz and a 128-Bit memory interface with 2 or 4 GB of GDDR5 memory at 1000 MHz (4000 MHz effective).
Architecture
The "Cape Verde" GPU codename is based on the Graphics Core Next (GCN) architecture and is processed in a 28 nm lithography. The GCN architecture features 10 processing units for a total of 640 stream processors. In addition, the AMD Radeon R9 M265X sports 40 texture units, 64 Z/Stencil ROP units, 16 color ROP units and a 512 KB L2 read/write cache.
The AMD Radeon R9 M265X is compatible with the lastest PCIe 3.0 Standard.
Performance
Depending on the clock rate (and maybe benefits from Boost), the AMD Radeon M265X ranks in the mid-range of mobile graphics cards as of mid 2014. Performance is sligthly above a GeForce 840M and a GeForce 940M. As a result, this AMD GPU can run current titles smoothly up to 900p with medium to high settings. Graphical settings will have to be reduced significantly when playing very demanding titles like Crysis 3 or Far Cry 3.
Features
A well-known feature of the AMD Radeon R9 M265X includes the “Eyefinity“ technology, which allows the user to connect up to 6 displays simultaneously. For notebooks, however, this feature is almost always limited by the number of available display ports.
The mid-range GPU also supports the “Enduro” technology for power efficiency, which is the counterpart to Nvidia's “Optimus”. While idle or in low load scenarios (Office, Internet, etc.), the system will deactivate the dGPU in favor of the more low-power integrated GPU.
The M265X also features the “Mantle” graphics API for gamers. This programming interface has been developed by the manufacturer as an alternative to Direct3D or OpenGL. Example titles with Mantle support include Battlefield 4, Thief, and The Sims 4 with more to come in the future.
With “App Acceleration”, AMD has also equipped the Radeon R9 M265X with technology for improving video quality and increasing application performance. However, support for OpenCL, DirectCompute, or DirectX video acceleration (DXVA) is required in order to use all described functions.
Power Consumption
With a TDP of about 35 to 40 Watt, the power consumption of the AMD Radeon R9 M265X ranges between the 840M (about 30 Watt) and the GTX 850M (~40 to 45 Watt). Thus, the graphics card is best suitable for 15-inch notebooks. Under low loads, automatic underclocking can save energy. When idle, the Enduro software can completely deactivate the card for additional power savings.
