AMD Readies Radeon HD 7730 Graphics Card

In an attempt to plug a hole in its product stack between the Radeon HD 7670 and the Radeon HD 7750, AMD could launch a new Radeon HD 7700 series SKU, the HD 7730. Based on the 28 nm "Cape Verde" silicon, the chip could feature 448 stream processors based on the Graphics CoreNext architecture, 28 TMUs, 16 ROPs, and a 128-bit wide GDDR5 memory interface, holding 1 GB of memory.

An MSI-branded HD 7730 is already doing rounds in the Chinese local market, indicating the SKU is designed for retail, and not just the OEM channel. The MSI card features 800 MHz core clock speed, with its memory clocked at 1125 MHz (4.50 GHz GDDR5-effective). With the HD 7730, AMD could also be going after NVIDIA's GeForce GT 640. It remains to be seen if the HD 7730 is a global product. The MSI card features retailer stickers from Taiwan-based retailers.

The source put the card through a few tests.

The printed package seems English, with stickers added for Chinese.

On a China only SKU wouldn't they print Chinese?
It's actually the Traditional Chinese characters which are used in Taiwan or Hong Kong.
In fact the contact no. on the sticker is the MSI Taiwan customer service hotline.
Thus I believe it's not China only SKU.:)

You get P1400-1800, depending on RAM performance, out of an AMD A10 5800K, unless you can CFX this GPU with the A10 it seems a bit pointless to release this just before Intel makes it even more obselete.
Intel makes what now? Have no fear not even Intel HD 5200 won't touch this, which mind you, will be pseudo-inexistent on the desktop market.


I'm betting on it being Richland hybrid CF-able... Seeing as how AMD is already planning on packing hybrid CF on Richland mobile with GCN GPUs up to HD 8730M...

It's not sub 100 USD, it starts at 100 USD retail at least it is here in the US.
I have 2 7750's - a full height model that I picked up last summer for about $75~$80 AR ($85~$90 before rebate) and a half height model I just picked up $89 AR ($99 before rebate).

That may be the case....with 896 SP's for the 7790 vs 448 SP's for the 7730 (i.e. 50%) it certainly looks like another Bonaire type chip. Would be a very economical use of the silicon and they should be fairly low power with decent performance.
448 shaders is half the Bonaire (7790); it's also 64 shaders less than the 7750 (and 192 less than the 7770) and 64 shaders = 1 computer unit in AMD's lingo. It could be a half-crippled Bonaire chip, it could also be a cut down Cape Verde with 3 CU's disabled.

Another thought is that this is a new chip. AMD likes to do the doubling thing with it's low and midrange chips - if you look at the 7770, 7870, both full feature chips, they've got 640 and 1280 chips. AMD/ATI did similar things with the 5000 series - the 5670 ran at 400 shaders, the 5770 ran at 800 shaders, and the 5870 had 1600 shaders. (This isn't really unique to AMD, though - it's a nice way of creating a differentiated product stack)

I thought Richland is the same/nearly the same silicon as Trinity but with better power usage tweaks and will have VLIW4 for the gpu portion. It might still crossfire with the GCN, though.

Well, A10-6700 (65W, 844MHz GPU) is between 20 and 30% faster than A10-5800K (100W, 800MHz GPU) in some leaked benches, so who knows exactly what magic they did there...


Also, as I've said, for mobile it's pretty much confirmed for Hybrid CF w/ GCN:

Sounds like the typical banter... there's no hole! The 7750 was their bottom retail model, (the 7670 is OEM-exclusive and just a rebadge). While like AMD really needs to compete with Nvidia's completely indeterminate and ridiculously overpriced GT640. AMD wanted to stay out of this market because they'd rather move APU's, but if they made it Hybrid C-F with decent results it could give them a boon on APU, and by selling a upgrade down the road. Honestly, I think they have copious quantities binned from early TSMC production of Cape Verde and might as well make some money.

Whatever this card ends-up (either Cape Verde or Bonaire) here in the States it will be a $50-75 with rebates in few weeks. The reference card's will be DDR5, but soon or right after they’ll be DDR3 and $50. I mean 7790's MSRP'd for $150, right now a nice MSI R7790-1GD5/OC is $110 –AR$25. What I'd say it would be interesting to see Bonaire get pinned AIB's to half-height PCB's and 50-60W TDP.

Lastly whatever Intel does for graphics for Haswell's with eDRAM, I don’t see it competing with the 7730.
