American fabless CPU and GPU designer, Texas-based company AMD is stealthily introducing a new revision of the HD 7750 GPU that has an increased default frequency. The reason for this move is either the recent Nvidia GTX 650 and 650 Ti launches that we reported here and here, or the simple fact that AMD’s GCN chips have very good yields.
We’re inclined to think that the motivation is a combination of the two.
The new cards are reportedly using the same cooling system, but they feature a slightly different PCB.
The cooling system has remained exactly the same, as the “Cape Verde” GPU is a very cool piece of technology when compared with other GPUs, but we would have liked to see more custom single-slot designs.
The PCB is a little larger, making it exactly like a HD 7770 PCB in dimensions and weight.
On the new HD 7750, the GPU is clocked at 900 MHz instead of the 800 Mhz we were used to see on the “older” HD 7750 video cards.
It seems like the price will stay the same so the casual gamers going for an AMD Radeon HD 7750 video card should enjoy the better performance for free.
The Radeon HD 7750 graphics processing unit is clocked at 900 MHz when working in full load 3D mode.
In 2D mode, the frequency of the GPU will drop to a low 300 MHz.
The GPU has a very small 123-square millimeter die size, containing 1.5 billion transistors containing 512 unified shader processors, 32 texturing units and 16 ROPs.
The “full” “Cape Verde” comes with 640 shaders and 40 texturing units, but that’s the Radeon HD 7770, and the HD 7750 version has some of the units inactive that add to the 100 MHz GPU frequency handicap.
