Preview: Gigabyte Radeon HD 7970 SOC Windforce 5X

By - Source: Tom's Hardware US | B 28 comments

Check out a sneak peek at Gigabyte's customized and overclocked Radeon HD 7970.

Based on AMD's Radeon HD 7970, Gigabyte's 7970 SOC Windforce 5X is an exotic card with an extreme approach that reminds us of the times when the company released, for example the 3D1 in 2005.

The 3-slot Windforce 5X has just completed a test run in our labs and we will be publishing a complete review shortly. We can already reveal that our reviewers were impressed by the effectiveness of the cooling solution that actively withdraws heat from the motherboard and guides directly to the outside of the case. Despite the increased power consumption of the card, which nears 300 watts under full load, but remains in the 200 to 225 watt range during gaming, the card does not burden the inside of a PC with greater heat dissipation.

After adjusting the card's vapor chamber, which originally had been developed for Gigabyte's GTX 680 card, our testers were able to increase the GPU clock of the Windforce 5X from 1080 MHz to 1300 MHz at 1.3 volts and the memory clock from 1375 MHz to 1500 MHz, using the 5x cooler solution of the card. The clock setting was enough to lift the 3DMark11 result in our test system to the top of the crop with a score of 3806, compared to a previous best of 3644 of the Galaxy/KFA2 GTX 680 EX OC at 1200 Mhz. 7970 SOC Windforce 5X topped the reference Radeon HD 7970 with a gain of about 13 percent.

Stay tuned for the full review here on Tom's Hardware.

    master_chenWhy would you do that!?

    for more gaming performance for those who would spend?

    So that you can fold more proteins than your friends?

    it is an interesting theory, who knows maybe in a few years all gpu fans will be setup like this.

    i'm more interrested in the amount noise it will produce. working on EMC vmax systems i know how much noise 8 X 40mm fans are capable of and i'm very optimistic, sounds like a mini jet on take off.

    Maybe, maybe not. Remember, with a heat sink this large, the fans might not need to push much air and thus might not need to spin quickly. Not spinning quickly means not much noise. Why don't you wait before passing judgement on a card that you've only seen pictures of?

    Kudos for exhausting heated air out of the case, can't wait for the full review

    I see you have never opened up your vmax though....The 40mm fans in your vmax are probably 60mm deep with 2 sets of blades made to push ungodly amounts of air noise be damned. They are fun fans to play with and draw like 25 watts a piece - MONSTERS.

    The fans used on this card however are the much more tame (and arguably useless) 10mm deep 40mm variety. I don't think it is even possible to make that size fan loud haha

    Mine more bitcoins too! Unless your friends get a FPGA or one of those soon to be(maybe) ASIC

    I hope they aren't in the future haha. While I'm sure it works and does look pretty interesting, I love the "classic" sleek look of a 5970.

    yeah thats why i said (8) X 40mm. from the front it looks like it has 4 fans but each fan assembly have 2 sets of blades in each. i didn't expect anyone to know that here lol. in EMCs defence though it isn't that loud in a cool(ish) room.

    Gosh i see all these crazy air cooling slotuions and im just perplexed as to why companies spend so much money developing these quirky ideas when they could do a poor job at watercooling one and achieve much higher performance. it just saddens me that its so hard to find water blocks for these non reference designs. guess i need to build a cnc
