The next graphics card in the Radeon HD 7000-series, the Radeon HD 7950, was just benchmarked by a Chinese website who found out that AMD’s upcoming solution is significantly faster than an Nvidia GeForce GTX 570M.
The Radeon HD 7950 graphics card used, which ran at AMD’s default frequencies, was paired together with an Intel Core i5-2500K processor and put through several loops of 3DMark 11.
At the end of these tests, AMD’s upcoming solution received a score of P6139 which puts it right between the last-gen HD 6970 and its older brother, the HD 7970 (the cards scored P5471 and P7728, respectively).
To see how the Radeon HD 7950 stacks up to its competition, the tester also run the 3DMark 11 benchmark on the same system but with an Nvidia GeForce GTX 580 graphics card installed, which returned a score of P5450.
This makes the GTX 570 about 12% slower than AMD’s upcoming GPU when both of these are run at their default clocks.
When the Radeon HD 7950 is overclocked, the difference can get a lot bigger since setting it at 1030MHz core/5,600MHz (1,400 MHz actual) memory returned a score P7056, which gets it just slightly behind the HD 7970.
The Radeon HD 7950 is based on the same graphics Core Next (GCN) architecture as its older brother, but this comes with four of the HD 7970’s Compute Units disabled to turn it into the Tahiti Pro.
The end result is a GPU that includes a total of 1792 stream processors (vs. 2048 in the HD 7970), 112 texture units, 32 ROP units and the same 384-bit wide bus of its elder brother.
The amount of memory installed also wasn’t modified so we are talking about the same 3GB of GDDR5 video buffer clocked at 1250MHz (5GHz data rate), while the GPU runs at 800MHz.
AMD hasn’t disclosed the release date of the Radeon HD 7950 so far, but some rumors suggest this will arrive on January 31. The HD 7950 is expected to be on average US $100-150 (77 to 116 EUR) cheaper than the HD 7970.
