Could some kind soul explain why the 5770 is cheaper than the 4890, considering it's a newer tech card?.

I've had some great help building my gaming system sofar, but I'm unsure with the GFX card purcahse. I have a XF ready mobo, but thats something for the future. Resolution I currently play at is 1680x1050, system specs below:

AMD Phenom II X4 Quad Core 955 Black Edition 3.20GHz (Socket AM3)
Asus M4A79XTD Evo
G.Skill Ripjaw 4GB (2x2GB) DDR3 PC3-12800C8 1600MHz Dual Channel Kit
Coolermaster Sileo 500 Silent Case - Black (500w Extreme Power Plus PSU)
Arctic Cooling Freezer 7 Pro Rev 2 CPU Cooler

Little lost in the graphics deprtment :D

the 5770 is a lower end card, it has dx-11 which is a bonus but the 4890 will out-perform on dx 10

Hmm. Bit odd to increase model number but be a lower speed/performance?.
I have read the 4890s seem to be the best card for sub £150. Just seemed odd that a newer card with similar speeds on the clocks would be better.

Sorry am looking at this from a noobs pov but:

Sapphire ATI Radeon HD 5770 Vapor-X 1024MB GDDR5 PCI-Express Graphics Card
Core: 860MHz, Memory: 1024MB 4800MHz GDDR5, Stream Processors: 800, DirectX 11 Support, ATI CrossFireX Ready, ATI Eyefinity, ATI Stream, ATI Avivo HD
£139.99


Sapphire ATI Radeon HD 4890 Vapor-X 1024MB GDDR5 PCI-Express Graphics Card
870MHz Core, 1024MB 4200MHz GDDR5 Memory, 800 Stream Processors, PCI-Express 2.0, CrossfireX Ready, Avivo HD, 7.1 Surround Sound
£164.99


Could you please illuminate why the 4890 is better?. remember I am a GFX noob.

Similar speeds on the clocks maybe, 128 bit memory bus though vs the 256 bit memory bus on the 4890. This does matter at higher resolutions, 1920x1080 up.
 
The 5770 is lower in performance than the 4890. The 5770 performs around about a 4870 card. However, it has DX11, is much cooler and quieter. If your'e gaming at 1680*1050, get a 5770 (it will be sufficient) - otherwise go for the 4890 if you don't care about the temps or power consumption.

The reason that the 5770 performs worse is probably mainly due to the very limited 128-bit bus
 
Think of the series as how new the card is and the last three numbers as performance indication. The 5770 is a newer card but the 4890 os the fastest single gpu in the HD4--- range.
 
At that res both cards will eat that up. Purely because its new tech I would get the 5770 and if and when you need extra power add another.
 
The 5770 are meant to perform very well in crossfire
also with new drivers the 5770 will start to perform even closer to the 4890.
 
Yeah I think the 5770 is best for me. I'm not after blistering performance and 150 fps in games, just a nice little runner, 5770 fits the bill.
 
It has a higher number, but doesn't mean it's more powerful.

If I'm correct then assuming WXYZ == 5770 then:
W = tech revision, higher is newer (I.E. 4000 series, 5000 series etc).
X = power level, the higher the better (5850 > 5750 for example).
Y = sub power level, the higher the better (5770 > 5750 for example).
Z = 0.

So, in this case the X is lower on the 5770 than the 4890, so it's less powerful... granted this isn't the case on the 4870... but yeah...

If that's incorrect, or someone can make it easier to understand (my choice of words are pretty poor I know) then correct me, but that's what I understand from the numbers :)

What confuses me is people making out like the power consumption/heat production from the last generation of ATI cards was ridiculously bad.

Yes, the 5000 series cards have been designed to produce less heat and consume less power but that doesn't mean to say the 4000 series were no good in comparison. I run two HD 4890s in crossfire and they idle at 30C and never go above 50C under heavy load. This is with the fan set at 30% when idle and 60% under load. That's not bad going if we're honest, certainly not enough to warrant going for a slower card that costs more. The only real attraction about a 5770 is the fact it will run games using DX11. Personally, i'm happier playing my games in DX10 and getting a good frame rate than i'd be playing them in DX11 with a bad to mediocre frame rate and paying more money.

More or less bang on.
- W = What you said.
- X = what area of the market the card is targeted at as well as what you said.
9 = Insane people ;) (5970)
8 = Gamers/Enthusiasts (5870)
7 = Mainstream (5770)
6 and below = Mainstream/Budget area HTPC's etc.
- Y = What you said.
- Z = Makes the number look rounded and pretty :)

Just a query, because I've been torn between getting a 5770 or a 4890, I've read a lot of reviews where people say the 4890 is very loud, power consumption isn't that much of a concern in my opinion, but fan volume is. %'s don't really tell me anything. Also, those temps seem a LOT lower than what I've read elsewhere, maybe you just got lucky and got a pair of nice cards? :p

The numbers he's getting are indeed impressive.

Noise on the 4890 hasn't been an issue for me, @100% the fan is loud but nothing besides benching pushes it that hard. I've got my fan sitting @ 60% for games, getting temps of 60 +/- 5 and it's pretty silent, only a teensy bit louder than my cpu cooler.

Am I really lucky? What cooler have you got on your card?

This is the card/cooler i have, got both from overclockersuk, and the picture is different on their site but this is the one you get when you order an XFX. Maybe it's the cooler on these cards?

Also, what case/case cooling are you using?

The card is pretty loud at anything above 70% fan speed, not stupidly loud mind. The way round this is to go into ATI catalyst and make two different profiles, one for gaming and one for idle. For idle i underclock the cards and stick the fan speed on 30% which is barely audible and they will sit at 30 - 35C. For Gaming i overclock the cards and stick the fan speed at 60% which isn't that loud at all, about the noise level of a light breeze hitting your window. I've never seen the cards go above 49C with these settings.

All i have to do is press Alt + I to go into idle mode or Alt + G to go into gaming mode. Happy days.

I think it's the cooler on the XFX cards is more efficient and quieter than the standard one, so if you're gonna go for a 4890, get this one:

See above for a picture of what you'll actually get.
 
Did a bit of research on that XFX HD 4890 and bought one. Not to fussed about the fan, I can get a cooler at a later date, budgets a bit thin at the moment ;)

I can at least have something that will stretch a little further in terms of longevity over the 5770, so £150 all in was a good deal.
 
I'm running a 5770 as a stop gap card and its damn impressive for the money. I would have got one of these.

DIRT 2 maxed out at 1920x1080 DX11 4xAA is very playable on ONE card.

The 5770 will use much less power than the 4890 especially at idle too.
