ATI Radeon HD 4770 review: The $100 Killer GPU?

Hot on the heels of last month's Radeon HD 4890 release which set a new performance record for ATI as their fastest single GPU yet, the company has another new graphics card for us today, this time targeting the sub-$100 market.

The new Radeon HD 4770 is the world's first 40nm graphics processing unit, and although it's not designed to set any speed records like the flagship 4890, the 4770 aims to deliver the best possible value in a neat cost-effective package.



It has become common practice for both ATI and Nvidia to make their initial migration to a new design process using a mid-range or even low-end GPU, allowing time for refinement before they push it to high-performance parts. That said, the Radeon HD 4770 is far from a simple affair as the GPU has a transistor count of 826 million, or just 14% less than the Radeon HD 4890, ATI's most complex GPU yet.

Can it crossfire with the 4800's?
#1.1 a1ien on 28 Apr 2009 - 12:47
of course not
#1.2 smooth_criminal1990 on 29 Apr 2009 - 21:23
err, I thought u could crossfire pretty much any ATI PCI-E card with each other??

@smooth_criminal1990

You are mistaken.

I know of hybrid crossfire but I don't know its extent, which is why I asked this question. For example, I can CFX a 4850 with my 4870 should I see reason.

If you got the amd 790x chipset, you can CrossFireX pretty much anything with everything.

Its effing ridiculous that a gfx card has too be that big.

The ones being sold dont have those heatsinks on them they have smaller ones. also the card barely uses more then what the pcie slot gives.

Have you not noticed that many cases have little plastic slots near the front of the case?

There use to be full-length cards (many of them ISA) that would stretch from one end of the case to the other.

Most cards now are a lot smaller than they use to be.

I wonder if there is a driver, hardware, or BIOS bug that is causing those high idle temps.

In theory it should clock down quite a bit and achieve similar temps as the 4670...that's the main reason I have one (I'd bump up to the next level, but temperatures and power consumption are higher than I'd like).

will it play crysis
#4.1 JulioFranco on 28 Apr 2009 - 15:53
Seems to deliver acceptable performance, but the test bed was Core i7 based (to remove any GPU bottlenecks) so performance with a more appropriate CPU should be lower than this:

That was never amusing, these days it's just a sign of a single digit IQ.

You do know we're talking about a graphics card, right?
I think asking whether a $100 dollar card will play Crysis is a very valid question.

Incorrect. Removing the CPU bottleneck is the best way to test, as it shows the pure performance of the card. Most cards will scale back in a pretty similar way with slower CPUs

Lot of talk about this card, if it's nearly as good as the hype then it's a bargain. Even more suprising that they're not charging over the odds in the UK!

One thing that concerns me though is the quality of ATI drivers. My last ATI card was back in pre-Vista days and drivers weren't great, not read up on whether they've improved any.
#5.1 Frank Fontaine on 02 May 2009 - 13:28
The current ATI drivers are pretty good actually, very stable and offer decent performance
#6 Lord Leveau on 29 Apr 2009 - 10:22
what kind of psu will two of these require in crossfire?
#7 ryoohki on 29 Apr 2009 - 19:13
Nice it have a AVG of 60 fps in in COD at 1920x1200, altought without FSAA or AF, that's the same FPS as the 360 version (at 1280x720) for a sub 100$ card it's very good!
#8 Anaron on 30 Apr 2009 - 04:39
The transistor count alone is 14% less than the HD 4890. If you ask me, that's quite a technological feat. Especially for a sub-$100 video card. The HD 4770 offers performance on level with the HD 4850, sometimes better and sometimes worse (depending on the game). The only "bad" thing I noticed is the 128-bit memory interface. That has severely crippled the card. It could do so much more! Then again, it hasn't hampered performance that much.

All in all, it's a nice and cheap package. AMD has done an amazing job with this video card. It's perhaps the best 128-bit video card around. Makes you wonder though, will AMD drop the prices of their other video cards? Namely the HD 4830 which, in about every case, is outperformed by the HD 4770. Ask anyone and they'll tell you that 4830 > 4770.

That sucks, I could of gotten this instead of my 4650!

What miffs me off:
Its $100 on ebay.com
Its £100 on ebay.co.uk

Still scamming the UK, nice one ati...
#10.1 +Tony. on 02 May 2009 - 16:28
Do remember that we have to pay tax plus the $ to £ inflation, don't look at ATi.
#10.2 Frank Fontaine on 02 May 2009 - 23:52
Indeed. nVidia cards on the whole tend to be even more expensive in the UK than ATI cards (pound for pound in similar performance brackets), so it isn't ATI's fault. Tech products all get marked up horribly in the UK thanks to our stupid government.
#11 MadCap on 03 May 2009 - 15:25
I'm guessing this would beat the pants off a 3850? Really makes me shake my head at the decrease in price and the increase in performance.
