also @ TechSpot: Nvidia GeForce GTX 780 Review
As first noted in a leaked roadmap last month and now seemingly confirmed by Chinese website EXPreview.com, AMD is scheduled to release their mid-range HD 7870 and 7850 series graphics cards based on the Pitcairn GPU in March. The latest leak reveals one Radeon HD 7870 and two Radeon HD 7850 cards; one with 1GB of memory and the other featuring 2GB.
Specifications for each card can be found below.
Radeon HD 7870
- 22 Graphics CoreNext Compute Units
- 1408 stream processors
- 88 TMUs
- 24 ROPs
- Memory bus of 256-bit
- Memory size of 2GB GDDR5 memory
- Clock speeds of 950 MHz core
- Memory frequency of 1375 MHz (5.50 GHz effective)
Radeon HD 7850
- 20 Graphics CoreNext Compute Units
- 1280 stream processors
- 80 TMUs
- 24 ROPs
- Memory Bus of 256-bit
- Memory size of 1 GB/2GB GDDR5 memory
- Clock speeds of 900 MHz core
- Memory frequency of 1250 MHz (5.00 GHz effective)
According to Tom's Hardware, early pricing for the HD 7870 is in the $300 ballpark while HD 7850 cards are expected to start around $220. It’s of course worth mentioning that these specifications aren’t official and even if they prove to be accurate, they only cover reference cards so we are likely to see manufacturers squeeze a bit more performance out of each via overclocking. We’ll likely know more come March 6 when CeBIT kicks off in Hanover, Germany.

AMD Radeon HD 7970 3GB GDDR5 PCIe
The AMD ATI Radeon HD 7970 measures 27 cm long (10.6 in), the GPU core is clocked at 925MHz, and the GDDR5 memory operates at the same frequency of 1375MHz (5.5GHz DDR). Still, pairing that frequency with a 384-bit memory bus gives the HD 7970 264GB/s of theoretical bandwidth. The HD 7970 carries 2048 SPUs, 128 TAUs and 32 ROPs, up 33% from 1536 SPUs and 96 TAUs, it's also the first PCI Express 3.0-compatible card.

With HD7950 only 15-20% faster than HD6970, what's the point of the HD7870 @ $299 exactly?
http://www.hardwarecanucks.com/forum/hardware-canucks-review
/51076-amd-radeon-hd-7950-review-tahiti-pro-arrives-24.htmlWith HD6950 2GB and GTX560 Ti 448 going for $225-250, the HD7800 series better overclock by 30-40% of it'll just turn out to be just another turd like the HD7770 is that gets whooped by HD6870 and GTX560.
-
hmm so it looks like the 7870 will give about equal performance to the 6970 based on the specs.
-
Poor mans cards. I want my GTX680s in SLI Fix in April with Ivy Bridge mmm good.

HD7950 should have been a $299 card and released as an HD7870. AMD should have upped the clocks by 30%+ and launched the "real" HD7950 and HD7970 cards with 1150+ mhz. Instead it feels like we got factory underclocked 7900 series, while AMD patiently waits for NV's response and releases HD7960 and HD7980 refreshes, while making benefiting from huge yields by launching HD7970 at only 925mhz.
Let's hope GK104 is faster than the HD7870 and comes in at $299 so we get some real competition and performance increases going.

Guys firstly this is a rumor. Secondly - if u were running the show at AMD u would do exactly what they doing now - take advantage of the few months between nvidias kepler launch and their current stock. When the nvidia range hits the shelves, rest assured the amd price will normalise.

The pricing right now for the 7000 series is atrocious but hey, can't blame AMD for doing what they're doing... they got their next gen cards to market first.

You would do really well in Sales and Marketing and bring nothing but financial profit and golden days for AMD or any other company with your awesome pricing suggestion.

^Finally someone with a business perspective. It's exactly what I would do. And besides, people are buying the 7970s because its still worth it for the money. Lower power consumption and performance.
All you other cheapos out there that doesn't want to fork out money can wait another year.

I'm eagerly awaiting the 1st 7850 with a non-reference cooler on it. I don't really care if it's 1GB or 2GB.
Hopefully I won't have to wait too long into March.
