The PowerColor Radeon HD 7850 SCS3 1GB video card is without a doubt an impressive looking card. You don't run across passive cards every day, let alone a mid-range AMD Radeon HD 7850 1GB card with the reference clock speeds left intact! PowerColor was very ambitious with this cards design, but did they hit a home run or a foul ball?
There a whole heap of partners that work with AMD to manufacture graphics cards and with the release of the 7790, I've looked at a card from virtually every major player in the market. It's very rare that this happens to be quite honest as I typically only see three or four cards at a time for each class of card but there's nothing wrong in breaking the mould a little and overall getting one of the most extensive data sets for Bonaire going.
PowerColor is a partner that I've not worked before, but this is not to say that their product is not worth looking at. The then ATI partner, who are owned by TUL, have been producing cards since 1997 and in some respects are a little unheard of these days when compared to the big names such as Asus and Gigabyte to name a few and be-known to some have also produced cards from NVIDIA, although this was done under the Zogis brand name.
With the release of the 7790, like may other partners, we see more than one SKU appear on the market by the brand with two slightly different overclock variants in that. The TurboDuo that I'm going to look over today is the faster and in a way, the better of the two, with a better cooling option and also a higher clock speed out of the box, but the real question is how does it stack up when pitted against the armada of 7790's that I've already seen and tested...
The new Radeon HD 7790 TurboDuo 1GB card from PowerColor features overclocking from the factory and a custom cooling system with two fans and a heatsink with a single heatpipe. The fan speed profile was tuned for achieving good temperatures and by raising the clocks even further from Catalyst Control Center, we can squeeze the last performance drop from the card.
We've been tracking AMD's HD 7730 for quite some time and now it is finally upon us. AMD's HD 7730 GPU is a cut-down version of the HD 7750 GPU and it uses a special Cape Verde LE GPU. This Cape Verde LE GPU is essentially a HD 7750 with two compute units out of eight switched off. This means the HD 7730 has 384 stream processors, 6 compute units, 24 texture units and 16 ROP units. It runs with default clocks of 800MHz on the core and 4.5GHz effective on the VRAM which is available in either 1GB of GDDR5 or 2GB of DDR3, note the 2GB DDR3 model runs at an effective memory speed of 1.8GHz. We have the 1GB GDDR5 model which despite having less frame buffer is much faster than the DDR3 equivalent because of the significantly greater memory bandwidth.
The HD 7730 is interesting because it features 384 GCN cores, much like the highest spec AMD Kaveri APU will feature when it comes out next year. So while this is a HD 7730 review, you should be able to get an idea of Kaveri's GPU performance based on this. Notably of the A10-7800K, if AMD follow the same naming pattern, as the A10-7800K will feature 384 GCN cores. The model we have here today is branded Powercolor but its pretty much as close to a reference design as you're going to get and will be one of the cheapest HD 7730s on the market. The HD 7730 will be priced in between the HD 6670 and the HD 7750. In the longer term it will phase out the ageing HD 6670. This card is totally powered by the motherboard and has a rated TDP of just 45W.
With the introduction of AMD's Cayman GPU, the Radeon HD 6870 video card becomes their flagship DirectX-11 desktop video card. Gamers can expect the PowerColor Radeon HD 6970 to quench their thirst for demanding graphics power while introducing several new MSAA modes such as Enhanced Quality Anti-Aliasing (EQAA). The PowerColor Radeon HD 6970 features enhanced DirectX 11 tessellation effects, while still producing top-end frame rates to help gamers build their killstreak. In addition to a new VLIW4 shader core architecture, the Cayman GPU also offers accelerated multimedia playback and transcoding, AMD HD3D stereoscopic technology, and the 3D Blu-ray multi-view CODEC (MVC). In this article, Benchmark Reviews tests graphical frame rate performance of the PowerColor AX6970 2GBD5-M2DH using the most demanding PC video game titles and benchmark software available.
PowerColor bringt mit der Radeon HD 6950 Vortex PCS+ eine Grafikkarte auf den Markt, deren Lüfter sich „ausfahren“ lässt. Ein echter Vorteil oder pure Spielerei? Das wollen wir in unserem heutigen Kurztest heraus finden. Zudem stellt sich die Frage, in wie weit die Karte darüber hinaus überzeugen kann.
One of the more impressive looking enhanced 6950s is the PowerColor PCS++ model and today we have one of those on our test bench. With an enhanced cooler and significantly increased specifications over the standard 6950 we will be putting it up against the GTX 570 and Radeon 6970 to see if it can compete with those, more expensive models.
Mit der Radeon HD 6950 PCS++ bringt PowerColor eine spezielle Grafikkarte auf den Markt: Sie diese lässt sich offiziell zu einer inoffiziellen Radeon HD 6970 freischalten. Dazu muss wie beim Referenzdesign lediglich der BIOS-Schalter auf dem PCB umgelegt werden und prompt kommen einem die zusätzlichen SIMD-Einheiten zu Gute.
Today we will be putting the 6950 PCS+ Vortex 2 and its unique cooler through a selection of real world gaming, multimedia and GPU computing tasks to see how it stacks up against some of the best competitor cards on the market.
It's been a while since we've looked at anything from PowerColor, but after seeing their showings at Computex, it's great to see something new from the company. Made even better is the fact that we're not talking about a card with a new cooler or anything like that, we're talking about a new card that PowerColor themselves have been working hard on.
