In February I reviewed several HD7750 and HD7770 graphics cards and was ultimately left with mixed feelings. I appreciated the commendable power consumption and modest heat output, but I felt that it was a sideways step for AMD. They seemed more focused on announcing that they had released the first graphics card at a ’1 GHZ clock speed’ while failing to highlight that they had stripped out a substantial amount of stream processors.
We're getting to that point where's it's been long enough after the launch of a new high-end video card model that we start to see companies mixing it up a bit and while XFX came out the gate early with the custom cooled Black Edition Double Dissipation model, we haven't seen anyone else do anything. Well, that's till today!
Today we're looking at the brand new Sapphire HD 7970 Dual-X 3GB OC which at the time of writing hasn't even shown up on the Sapphire website yet. That gives you an idea of just how new the model is and just how quickly we're able to get ahold of it thanks to being based out of Taiwan now.
First we checked out the XFX offering which was called the HD 7770 Black Edition S Super Overclocked, then we looked at the Sapphire card and discovered it carried with it a similar strong overclock and we tested the new model in CrossFire.
From there we moved away from the HD 7770 and looked at the HIS HD 7750 1GB to see how the new HD 7700 series was rounded out. If that wasn't enough of the new HD 7700 series we also checked out the dual fan MSI HD 7770 and proceeded to see how high we could overclock the model. After all that was done and I found myself looking at the reference HD 7770 we have here today from AMD. I realized that we actually haven't looked at reference clock performance of the new model.
We reviewed the reference AMD HD7970 flagship card in December last year and we were suitably impressed. A few weeks later XFX sent us their XFX R7970 Double Dissipation graphics card which featured a custom cooling solution. Today we look at the latest version of the card from partner VTX3D – The ‘HD7970 X Edition’ is the first HD7970 we have reviewed which features not only a modified cooler, but overclocked core clock and memory speeds. Is this good enough to get the Kitguru seal of approval?
Since we knew that the Catalyst 12.2 drivers weren't far away we figured it was a good chance to look at the driver in a bit more detail than just our typical Catalyst benchmark line up, so that's exactly what we'll be doing today as we see how the Diamond HD 7970 with the series' first WHQL driver goes against the original launch driver we used.
Of course there are a few things we need to do before we get into the performance side of things and we see exactly what's going on with the latest AMD driver. Since we haven't looked at the Diamond HD 7970, the first thing we need to do is take a closer look at the bundle to see exactly what's going on.
We have one of the first retail 7800 cards available to us in the form of Sapphires 7850 OverClock Edition. Today we will be putting it head to head with the GTX 560 Ti Overclock in order to find out which comes out on top. Tests include Battlefield 3, Skyrim and The Old Republic along with the usual media, GPU computing and power/temperature results.
Sapphire are readying their 7870 cards and first out of the gate is their custom design OverClock Edition. We have one on our test bench today and here is a gallery which shows what Sapphire are offering.
The Gigabyte Radeon HD 7770 OC (GV-R777OC-1GD) is a custom AMD Radeon HD 7770 video card that uses a custom PCB and GPU cooler to make it stand out from the rest. It is also factory overclocked to 1100 MHz on the core clock to ensure that it is faster than the reference design. Radeon on to see how this video card does when compared to two other Radeon HD 7770 cards on our test bench. We also overclock it further and see how the custom GPU cooler does!
3DMark 11 fired up and froze straight away. All of a sudden I found myself with something that was going to become real boring, real quickly. Of course it then clicked that just because we don't have a CrossFire connector it doesn't mean CrossFire can't be used.
Looking at the AMD website for the HD 7750 you'll find that CrossFire is of course supported on the model and I figured why not pair it up with our HIS HD 7750 we looked at and see what kind of performance we can get. It would be interesting to see what would go down with CrossFire scaling on this lower end model which carried with it no CrossFire bridge.
Juste avant les fêtes de fin d'année, AMD dévoilait son nouveau GPU phare, Tahiti, dans sa version intégrale sur la HD 7970, puis dans une version légèrement amputée avec la HD 7950 un mois plus tard. Ces puces employant la nouvelle architecture GCN qui fait la part belle aux unités de calcul vectorielles à l'instar du concurrent historique, en profit ent pour étrenner une finesse de gravure inédite (28 nm) et quelques autres nouveautés à l'image du jeu d'instructions DX11.1 et du PCIE dans sa révision 3. Avant même que le caméléon n'ait eu la possibilité de répliquer à cette offensive sur le haut de gamme, AMD déroule sa Road Map des puces "Southern Islands" avec Cape Verde situé à l'autre extrémité de l'échelle des performances, le fondeur ayant décidé de ne pas lancer de puce d'entrée de gamme sur cette génération, réservant ce créneau à ces APU et ses HD 6600. Que valent donc les HD 7700 équipées de ce GPU et destinées au volumineux segment de marché "Mainstream" ?
