AMD has prepared new weapons against NVIDIA, which will keep the new Radeon offensive going strong at least for the time being. On February 15, AMD will announce two new members of the 7-th generation Radeon graphics cards – the AMD Radeon HD 7750 and Radeon HD 7770.
The novelties will carry the Cape Verde code name and will become the most affordable AMD 7-th generation graphics cards built on the new Graphics Core Next Architecture (GCN). The Radeon HD 7770 is expected to cost around 129 USD in the USA, while the slower HD 7750 video card is expected to retail for around 100-110 USD.
As to the specs the new Radeon HD 7770 will offer 40 texture units and 640 stream processors, coupled with 16 ROP blocks. The core will run at 1000 MHz, while the 1 GB GDDR5 memory will run at 4500 MHz and will be accessed via a 128-bit bus, offering 72 GB/sec of memory bandwidth. Power consumption will be 80 watts.
The slower Radeon HD 7750 will offer 32 texture units, 512 stream processors and 16 ROP blocks. The GPU will run at 700 MHz, while the 1 GB GDDR5 memory will be again clocked at 4500 MHz thus offering 72 GB/sec of memory bandwidth over a 128-bit bus. Power consumption will be 55 watts.
Preliminary benchmark tests show that the Radeon HD 7770 will be equal to Radeon HD 6850 and faster than Radeon HD 6790 and NVIDIA GeForce GTX 550Ti. The Radeon HD 7750 on the other hand is as fast as the Radeon HD 6770 and GeForce GTX 550 Ti.
