HIS’s upcoming Radeon HD 7970 X2 graphics card which makes use of Dual Tahiti cores has been unveiled and bencmarked by TomsHardware. The HIS Radeon HD 7970 X2 was pictured back at Computex 2012, the version we saw back then was an early sample according to Toms while the one they reviewed is the final retail iteration which would be available to consumers shortly.
HIS Radeon HD 7970 X2 Specifications:
The HIS Radeon HD 7970 X2 is powered by Dual Tahiti Cores with a total of 4096 Stream Processors (2048 on each core), 6 GB GDDR5 memory (3 GB on each bank) running across an 384-bit x2 memory interface. The Tahiti Cores are linked together via the Lucidlogix LT22102 chip which is limited to PCI-e 2.0, but looking from the benchmarks there is not much of a performance affect caused by that.
HIS Radeon HD 7970 X2 makes use of a 6+2 Phase VRM for core and memory respectively. This mean that the PCB in total features a 16 Phase VRM which is comparable to the TUL’s HD 7990 offering. Both Tahiti Cores are clocked at 1050 MHz compared to 1000 MHz on TUL’s HD 7990. The GPU is powered by three 8-Pin PCI-e connectors resulting in a TDP of around 500W (150W+150W+150W+75W). Display outputs include four mini display, 1 HDMI and a single DVI output. The card can also be Crossfire’d with another HD 7970 X2 through a single Crossfire gold finger situated on the PCB.
Coming to the cooling design, the card uses a tri-slot cooler equipped with Dual 95mm fans placed right on top of the Tahiti cores. Underneath each fan is a relatively large aluminum fin array block with copper base and 6 copper heatpipes pushing the heat produced by the cores. HIS has put several vents along the sides of the shroud which would blow out the hot air inside the case, so a side-fan on the chassis would be compulsory if you don’t want your other PC hardware getting heated up.
HIS Radeon HD 7970 X2 Benchmarks:
Following our a few benchmarks which show the overall performance of HIS Radeon HD 7970 X2 against TUL’s Radeon HD 7990 and NVIDIA’s GeForce GTX 690. For full review, head over to Tomshardware. Tom’s however did not unveil the price nor release date but we think we would know it soon, as for the benchmarks, HIS Radeon HD 7970 X2 surely shows the other two dual chip cards who’s the boss when it comes to raw GPU performance.
