On February 15, AMD seems set to introduce its next series of graphics cards based on the Generation Core Next (GCN) architecture, which will be released into the Radeon HD 7700 series and target the mainstream market.For starters, the Radeon HD 7700 lineup will include two video cards, the HD 7770 and the HD7750, both of these using AMD’s Cape Verde graphics core.
Sadly, MSI roadmap isn’t all that informative when it comes to detailing the specs of these two cards, but it does however reveal that both of AMD’s solutions will pack 1GB of GDDR5 memory.
In order to learn more about the two Cape Verde GPUs, we have to turn our attention to some older leaks that were published at the end of last year.
According to this info, the Cape Verde XT features 896 streaming processors, 56 texture units and 16 ROP units, all connected to the video buffer via a 128-bit wide memory bus.
Speaking about the memory, this will be clocked at 1,375MHz (5.5GHz data rate) in order to deliver 88GB/s of bandwidth, while the GPU operating frequency is set at 900MHz.
Moving to the Cape Verde Pro GPU used inside the Radeon HD 7750, this will also work at 900MHz, but AMD decided to set the memory at 1,250MHz (5GHz effective), while including the same 128-bit bus in order to deliver 80GB/s of theoretical bandwidth.
The number of ROP units wasn’t modified either, but the GPU now features 832 stream processors and 52 texture units.
According to the leaked MSI roadmap published by CPU-World, both of these graphics cards will be made official on February 15, with an MSRP of $149 and $139 (113 and 105 EUR), respectively.
