Advanced Micro Devices (AMD) has announced three new mobile graphics chips that will power the next generation of notebooks. The models are known as Radeon R5 M230, Radeon R7 M265 and Radeon R9 M290X.
As the name suggests the Radeon R5 M230 is the slowest chip of all three. This one comes with 320 stream processors, 20 texture units, 4 ROPs and a 64-bit memory controller that will address regular DDR3 memory. The GPU supports up to 4 GB of memory and runs at 855 MHz.
The Radeon R7 M265 offers 384 stream processors and runs at 850 MHz that goes up to 900 MHz in Turbo mode. The chip is also provided with a GDDR5 memory controller that supports up to 2 GB of GDDR5 memory.
The last GPU, which is the most powerful of the three, should bring more excitement but unfortunately it does not deliver as much. In a few words the Radeon R9 M290X is a rebranded Radeon HD 8970M as rumored before. Still the new old GPU will bring some more performance as it offers a bit higher clock speeds than before. It comes with 1280 stream processors, 80 texture units, 32 ROPs and up to 4 GB of GDDR5 memory that is accessed over a 256-bit memory bus. The GPU runs at 900 MHz, while the memory operates at 4800 MHz.
The new AMD GPU families will soon get more members for sure.
