The mainstream AMD Radeon HD 7800-series has launched, in the forms of two cards: HD 7850 and HD 7870. It seems as though these cards pack quite the power for their price, with performance per Watt quite high.
The HD 7870, according to benchmarks, seems to keep up with cards like the GeForce GTX 580 in Metro 2033, and only lose out to its bigger brothers in the HD 7950 and HD 7950 by a few frames per second. Quite the amazing card if I do say so myself! Check out the reviews below:

VR-Zone have an interesting piece on the power circuitry within NVIDIA's upcoming Kepler GPU, and it reveals some juicy info. First up, NVIDIA is tapping the supply chain maker Foxconn to manufacture the high-end Kepler-based GPUs, and according to sources, NVIDIA has used the strategy of switching between Flextronics and Foxconn in the past, but are now happy with Foxconn.
The board talked about was manufactured in Q3 of last year, which would lead us to believe that NVIDIA have had Kepler GPUs for a while now. Kepler was meant to see the light of day in 2011, with Maxwell hitting in 2013, but that won't be happening now. It's obvious that yields were low once again for NVIDIA, which is why they would've stopped from pushing Kepler cards into production. In NVIDIA's recent financial analyst call, the can-of-whoop-ass himself Jen-Hsun stated that the 28nm supply will be "constrained through the year (2012)".
The diagram above shows that the board in question (GeForce GTX 670 Ti) requires a single six-pin and eight-pin power cables, which gives us 75W + 150W + 75W = 300W total, even though it should still work with just two six-pin rails. Three phases are dedicated to feed the GPU, and dual phase is for the rest of the board. VR-Zone say they'll continue to post articles covering this in the future, while I wait with anticipation.
Team Green is hard at work on their Kepler GPUs, which are based on a 28nm process, and it seems as though the GK104 part is going to be called the GeForce GTX 670 Ti.
NVIDIA is obviously keen to get this part onto shelves now, to combat the GCN-based AMD Radeon HD 79x0 parts, and this could be way the otherwise mid-range SKU has been changed from what should've been the GTX 660 to the GTX 670 Ti. This move could be so that it indicates this part will perform competitively against the high-end parts already on the market, such as the HD 7000-series.
Sources have told SweClockers that they expect the GK104-based GeForce GTX 670 Ti to outperform the GeForce GTX 580 and Radeon HD 7950. techPowerUp are reporting they're hearing rumblings of a March launch, and if NVIDIA want to beat the HD 7800-series launch, they'll have to wave that Team Green flag, now.
EXPreview have posted some interesting news/rumor/talk about the upcoming 28nm-based NVIDIA Kepler GPUs where forum friend of EXPreview "phk" posted an article saying:
During the week of March 15th, there comes with spot goods, NVIDIA won't follow AMD in spite of tight schedule.
Although phk doesn't state which product/s will debut, it should be an NVIDIA Kepler-based product. Whether this will be a paper launch, or a proper launch, I guess we'll have to wait and see. NVIDIA will need to release something, because if they don't, AMD will have a near top-to-bottom release of their GCN-based cards before NVIDIA even drops a single Kepler GPU. Can Team Green do it?
AMD have had their launch of their Radeon 7900-series, and now its time for the next Graphics CoreNext cards to be unveiled, the "Pitcairn" cards. The Pitcairn cards will slot into the Radeon HD 7800-series, where we'll see three SKUs from this series.
First up we'll have the Radeon HD 7870, then a 2GB 7850 and a 1GB 7850. Spec-wise, we have:
Radeon HD 7870
- 22 GCN CUs, 1408 stream processors
- 88 TMUs, 24 ROPs (de-linked from memory bus)
- 256-bit wide GDDR5 memory interface, 2 GB
- Clock speeds of 950 MHz core, 1375 MHz (5.50 GHz effective) memory
Radeon HD 7850
- 20 Graphics CoreNext Compute Units, 1280 stream processors
- 80 TMUs, 24 ROPs (de-linked from the memory bus, of course)
- 256-bit wide GDDR5 memory interface, 2 GB and 1 GB variants
- Clock speeds of 900 MHz core, 1250 MHz (5.00 GHz effective) memory
NVIDIA rebrands again, and is set to release the 6th member of the desktop GTX 560 family, which will enjoy giving presents to the following GPUs on Christmas: GTX 560 Ti, GTX 560, GTX 560 Ti (OEM), GTX 560 (OEM) and GTX 560 Ti 448 Core.
But, the GTX 560 SE seems to fall in line more with the OEM GTX 555 than those GPUs. The GTX 560 SE is made from a GF114 derivative, but with 2 SMs disabled which brings it to a total of 288 SP and 48 TMU. Core clocks will be placed at 776MHz, with shaders placed at 1552MHz. 1 MC is disabled, which gives the GTX 560 SE a memory interface of 192-bit, with 3828MHz 1GB GDDR5 with a total bandwidth of 92GB/sec.
The new GTX 560 SE is expected to offer performance similar to that of the GTX 555 OEM, and is looking to go into the ring against the quite-amazing AMD Radeon HD 7770. It will be priced quite competitively, at the $150-mark, but won't match AMD's amazing performance/watt ratio.
AMD's first super-affordable Graphics Core Next-based, 28nm GPUs are here in the form of the AMD Radeon HD 7770 and HD 7750. They offer some really impressive value for money.
The new GPUs are in the under-$199 category, which is perfect for budget-concious gamers. The HD 7770 seems to keep up and sometimes beat the already-great NVIDIA GeForce GTX 560 Ti card, which is something truly amazing considering it's maximum power consumption comes in at under 85W. Yes, under 85W. For comparison sake, the GTX 560 Ti uses over 215W.
Take a look at some of the reviews of the new GPU below:
I'm a sucker for GPU-related anything, really. I've reported a few times on rumors or news of NVIDIA's upcoming 28nm spin dubbed "Kepler", with the GK104 part being the mid-range power-house that should have the socks of most people being knocked off, if they can get it right. NVIDIA have been rumored to launch some cards in the March/April time frame and it seems this could be correct.
First off, as always, here's some salt. Let's get into it: SemiAccurate are reporting that GK104 Kepler GPUs are in the wild, and are being testing by AIB's (add-in board partners).

PowerColor have teased everyone on their Facebook page with a glimpse of their new AMD Radeon HD 7970 GPU. Nothing more than it's "our new HD 7970 design posing for the camera" has been said from PowerColor.
What we can see though, are multiple video outputs, looks like the new HD 7970 from PowerColor sports dual DVI, HDMI, and dual DisplayPort. The card is still a dual-slot card, with two big fans on the front of it and a decently thick heatpipe design behind it.
More information on this bad boy as it comes. I do like the black/blue design of it. Reminds me of getting a bruise. This could could be powerful enough to punch the lights out of other HD 7970s, and give them... bruises? We'll find out soon enough. Hopefully our VGA editor is out of hospital by then, but I'm sure he's enjoying his Razer Blade gaming laptop too much, eh? ;)
