HD4650 - poor man 256-bit board

Well well, look at this. AMD launches the ATI FirePro V5700 which has 320 streamprocessors, a 128-bit memory interface, UVD2.0 and the supposed HD4650 cooler shown in the first post of this topic:



RV730 anyone?

Edit: Confirmed it's RV730. Look at the backside. Green sticker. Clearly says RV730

 

I think the ring bus puts the dampener on that theory.

I edited my post. Check the green sticker:

ASIC Type: RV730

And the AMD site is known to have the wrong specs all over the place... it says V3700 also has a ringbus and afaik RV515/RV610/RV620 didn't have the ringbus. Oh and it says 128-bit ringbus... shouldn't it have a 256-bit ringbus if it has a 128-bit memory interface? Looks like someone messed up while copy and pasting?

 

Yes, I discovered your edit after posting. No doubt there.

Normally the Fire cards are much later than the consumer cards - so this is really surprising.

The press release also mentions UVD2.0 so there's really no doubt:

and yes, AMD's site tends to be erroneous.

The RV670 FireGL card came out before the Radeon.

 

Was it actually launched or merely announced? It turns out that FirePro V5700 isn't launching until September. I seem to remember that the non-consumer RV670s took ages to arrive commercially.

Also, FirePro appears to be a new brand, launched today.

Hmm
Specs & reviews were out, don't know about actual hardware though?

 

3D Professor has also confirmed that the ATI FirePro 5700 is "R730" (I'm assuming this was a typo and should be and/or refer to what is understood to be RV730) in their preview. In it's FirePro 5700 configuration, RV730 features 320 stream processors and a 128-bit memory bus (28.8GB/s).

There's also a short interview with Janet Matsuda who is Senior Director Professional Graphics for the ATI FirePro Division.

ATI Radeon HD4670 512MB Pictures disclosed

V5700 with new sticker?

I do not think this will be reference board, since I see no big sence in offering 2 Displayports on a mainstream-card, while many user still have analog connected LCDs or want to connect TV.

Still GDDR3 for the HD4670?

And this seems to hurt performance (Vantage below HD3850), while with GDDR5 and 8 RV770 ROPs it should be possible to be >3850, but maybe we will see this on another SKU later this year, when all vendors offer GDDR5.

 

I don't think 512MB of GDDR5 is viable for a sub $100 card yet.

 

A 192mm² die and a 256-Bit PCB with 8 memory devices seem to be viable.
Why not a 150mm² die with a 128-Bit PCB and only 4 1024Mbit memory devices? (Not forget about 4870X2 with 16*1024MBit GDDR5, 2x256mm² dies, PCIe2-switch, big cooper-cooler and >10 layer PCB for $549... )

But lets see, RV730 (and later shrinked to 45/40nm as RV740) should be rest longer market, so they may do a refresh in times when GDDR5 is cheaper and available in higher quantities...

 

Not only. There are even better price/performance options - e.g. DDR3

 

The 38x0 is hardly designed for the sub $100 segment, I think the margins are pretty thin.

Yes the 4870x2 is pretty cheap, i doubt it has stellar margins (but a the marked for $700 cards is tiny).

Yes I think GDDR5 prices will come down pretty fast, when the demand has stabilized a bit (supply will keep going up).

The upcomming launch of the 1GB 4870 indicates that the price/supply situation of GDDR5 has improved since the original 4870 launch.

 

HD4600 reviewed -- there is a hint of texture filtering in a G80 "style"!

Summary performance chart here.

 

Woah, hang on a second, have you seen the TUs?!! There's double the filtering units per TU. So it achieves 32 texels per clock not by having 8 quad TUs (i.e. 8 clusters) but with 4 8-way TUs.

9500GT is utterly outclassed, as expected. ~50-166% faster, with 24% more die area. 9500GTs look like they can be overclocked to perform about 30% better, not sure what 9550GT will achieve though.

Not quite as fast as the 3850 (which is what I was hoping for), but a good deal faster than the previous 3600 series (3690 special EOL part aside).

 

2400/2600/3450/3650 didn't get enough heat for how much they sucked. I suppose that AMD priced them appropriately helped that though.

 

A blueprint for R800, eh?
