AMD Radeon HD 7970 GHz Edition review roundup: a big, bad bruiser of a graphics card
You know the routine: we looked this revamped card's spec sheet a few hours ago, so now it's time to find out how it fared in independent tests and whether it's worth the $499 outlay. On the face of it, this powerhouse of a card ought to be a champ, since it comes $50 cheaper than the original's launch price (although that non-GHz Edition has now dropped to $449) and brings crucial improvements in clock speed and memory bandwidth. In practice? Well, it wins -- but only on points. Read on for more.
AMD launches Radeon HD 7970 GHz Edition, demands rematch with NVIDIA
If you've been missing out on the graphics card wars of late, then here's a quick rundown. AMD launched its high-end $549 Radeon HD 7970 at the end of last year, and it reigned comfortably for a few months until NVIDIA came out with the masterful GeForce GTX 680. That would have been the end of the matter, at least for this product cycle, except for one crucial factor: time. Having reached the market so much earlier, AMD has now had six months to not only tweak its drivers but also its 28nm silicon. That process has already culminated in 1GHz cards at the low- and mid-ranges, and today it leads to the (slightly predictable) announcement of a Radeon HD 7970 'GHz Edition' -- priced at $499 and expected to be available from a range of board makers from next week. To keep you amused in the meantime, there's plenty of detail in the gallery below and after the break. Update: review roundup added here.%Gallery-158843%
AMD Radeon HD 7970 could get 'GHz Edition', put the hurtz on NVIDIA
AMD's Radeon HD 7770 and 7870 reference cards already sport 1GHz clock speeds, but so far the high-end flagship 7970 has been stuck at 925MHz. That'd be no big deal, perhaps, were it not for rival NVIDIA's benchmark-stealing GeForce GTX 680, which autonomously adjusts its clock speed on the fly and easily hits 1.2GHz under the right conditions. But while NVIDIA has yet to roll out its full stack of 28nm cards, AMD is finding plenty of time to play catch-up. According to Australian site Atomic MPC, the company has revealed that the manufacturing process of its next-gen GPUs has improved to the point where the same average voltages can yield much higher clock speeds. Recent chips can reach 1.25GHz without struggling, which means a conservative "GHz Edition" of the 7970 can now safely be rolled out, of course with scope for much higher overclocking on third-party boards with more robust coolers. By the time the battle between Red and Green reaches full-swing, it might not be so easy to call a winner.
