Reviews - PowerColor Radeon HD 7770 and AMD Radeon HD 7750

[Terbinator]

To be fair, that's similar pricing to the first round of HD5670 GDDR5 cards, which (iirc) started in the mid £70s and went up to the low £90s - so assuming the 7750 gives 5750 levels of performance, in a bus powered card, at a lower launch price (from memory the 5750 launched at ~ £100), that doesn't strike me as too bad. All the more reason to want a 7750 vs 6750 vs 6670 comparison though

*EDIT* I note with some dismay that the Gigabyte and Sapphire HD7750s both use dual slot coolers This is a 55W card, that could easily be cooled passively: why the big chunky fansinks?!

Lol wait?

I hope the 78xx series is less disappointing than this! Otherwise WTH am I waiting for, I could just drop £180-220 on a 'last gen' 6950 or 560Ti now and laugh at the bound-to-be-ridiculous new gen prices when they do arrive.

I was being sarcastic.
While i do like the idea of single-slot cards i can imagine them being fairly loud under the kosh.

I suppose that is a trade off for a more compact card.

The HD7750 seems to be 40% faster than an HD6670 and consumes less power:

Eh??

More e-peen marketeers ride in to fail the day!!

Yep.

There was a mobo manufacturer that admitted that much of its heatsinks were not needed, but they found them being there improved perception of the product. I have a feeling its a similar case with those graphics cards.

Keep forgetting about Anandtech bench

So, 7750 is a slightly better all round card than the 5/6750, is bus powered, and costs less than the 5750 did at launch? In that case it's not a bad launch for the top end bus-powered card. If / when the price comes down nearer £70 it'll be a good buy, I reckon. Overclocking potential is going to be constrained by the 75W limit of the PCIe slot (wonder if the reason hexus' overclocking results didn't show through was powerplay throttling the GPU to keep it within TDP?), but it looks like a decent card for an HTPC with occasional gaming...

[Terbinator]

I'm surprised it (both cards at that) can pull 30FPS @ 1050p in BF3. But more surprising is that there is then such a discrepancy between the 5750 and the 7750 in Skyrim.

[scaryjim]

Presumably Skyrim uses a compute-heavy DX11 call somewhere that slows the 5750 right down - it's the 1080p *very* high quality where the 5750 really suffers, so presumably it's one of the extra settings between that and the normal high quality that makes the difference. There's obviously some games where GCN has a significant advantage over VLIW (and not just the games with dubious levels of invisible tessellation *ahem*Crysis2*ahem*)

[Terbinator]

Snip...

Skyrim is DX9.

[Brewster0101]

These will fall in price to below £100 once supplies are flowing at fall pace and the mid range 78xx series are released. Its early days in the next generation of graphics cards and ATI/AMD are just milking the money a little while they can - can't blame them.

Civ5 seem to do very well on the HD7750 and HD7770:

It also seems to do very well in Skyrim at 1920X1080:

Skyrim is DX9.

Seriously? *just* DX9? wtf? What is this, 2005?

So is The Witcher 2 and it looks gorgeous.

Although there is a DX10 folder tucked away in the Skyrim directory.

[CAT-THE-FIFTH]

Even Borderlands has a DX10 mode which cannot be accessed through the main menu(I think).

[Hicks12]

skyrim is on the dx9 version however it has taken small parts from dx10 if i remember rightly thats what the lead developer said...

Can i ask, when was this review done guys? I only ask as that BF3 had a patch yesterday (evening) and it was to fix a couple of crashes and to... IMPROVE PERFORMANCE OF 7000 SERIES!

(if you havent tested after that patch... can you test the 7970/50 again please ).

Looks like a pretty unexciting launch, cant even best my gtx460... great .

Makes sense though as the UE3 has supported DX10 since a while back.

ocuk and ebuyer both have the 7750 for under £85 allready
