And speaking of MST hubs, we’ve been waiting on them for quite some time now given that AMD has supported DisplayPort 1.2 for nearly a year.
The choice in DisplayPorts is significant as Turks brings with it DisplayPort 1.2 compatibility, which means the V4900 can be used to drive up to 6 monitors in Eyefinity mode when paired with MST hubs. Meanwhile for the port configuration on the V4900 AMD has gone with something more traditional for the FirePro market, equipping the card with 1 DVI port and 2 full size DisplayPorts. Compared to its desktop counterpart though AMD has gone with an entirely different form factor for the V4900, opting to use a full-height single slot card with an active cooler. AMD officially classifies the V4900 as having a sub-75W TDP, though giving the similarities to the Radeon HD 6670 it should be right around 66W. The V4900 is for all practical purposes a GDDR5 Radeon HD 6670 when it comes to hardware, running at the same 800MHz core clock and 1GHz (4GHz data rate) memory clock as its consumer counterpart. Since AMD keeps fewer FirePro cards than they do desktop Radeon cards, only a single variant of Turks will be launching as a FirePro card. All of these features will be available in the V4900, and in spite of these improvements Turks still comes within a few watts of Redwood’s power budget, making the Turks based V4900 a drop-in replacement for the Redwood based V4800. Turks also brought with it the rest of feature improvements we saw with the Northern Islands GPUs: primarily support for DisplayPort 1.2 and color calibration in linear space, while UVD 3 is also present for video decoding purposes. With respect to performance Turks moves from 5 SIMDs (400 SPs) to 6 SIMDs (480 SPs), which gives it an immediate 20% compute and texture advantage over Redwood at the same clocks. As you may recall from Turks’ desktop launch, Turks improves on Redwood in a few different ways.
In May of this year we saw the introduction of the Cayman based FirePro V7900 and V5900, and now just a bit over 6 months after the Turks based Radeon 65 launched, Turks is getting the professional graphics treatment with the FirePro V4900.Īs Turks was designed to replace the older Redwood GPU, so too is the FirePro V4900 designed to replace the FirePro 3D V4800 (AMD has dropped the 3D moniker). Nowhere is this more evident than their professional graphics lineup, where consumer desktop video cards have transitioned over to professional products at almost 6 months on the dot. For the last couple of years AMD has been pretty consistent about cascading their GPUs through their entire product line.
