ASUS Radeon HD 5770 Benchmarked

Everyone that keeps comparing the nV cards to the ATi cards keeps talking about the low bus width. It's been low forever guys, several generations of cards in fact.
Don't you think that the engineers that came up with the GPU of this complexity would figure out the bus width they need by now?:shadedshu
If it's limiting did you ever figure that maybe it's supposed to do so by their planning?
*rant complete*
Sorry everyone, but I had to release that after hearing this age old argument that has all but made my eyes and ears bleed.:mad:

I haven't seen anyone comparing this card to any Nvidia card. They have compared it to the HD4890, a card that has exactly the same specs of the HD5770 except for the memory bus. That is a fact, a hard fact and it's slower, hence anyone can conclude it is because of the memory bandwidth. 3Dmarks are less memory dependant than games in general so the difference might be bigger in games. We'll see when Wizzard makes his review.

True

Everyone, expect massive bumps in performance once you up the memory clock.

The gains must be large for such a shader powerfull videocard!
 
It's easy to simulate the performance. You just have to drop the mem clocks of a HD4890 down to simulate the supposed bandwidth of ~77GB/s
 
Wow that 128-bit interface put this card in bad times.
 
based on the battleforge DX11 benchmark for the HD5870 DX11 performs better than DX10 with more features, but yea this card is a gamble, still, if the HD4870 price drops to like 100 bucks I will probably buy one for sure.

I've decided to take advantage of the old tech. An XFX 1G for 145 -20 for MIR, is more than I can resist. I can almost replace all 3 of my 3870's with one card. Next payday it will be two 4870's.

Thanx to ATI for releasing quality products and lowering the prices of their older stock.:D

I will build a new gaming rig in the summer and take advantage of DX11 at that point and time. I still run 98SE on one section and don't know how a DX11 card would like that.

strange my old 2x 3870's match my 4870 512 when i had it
 
Whatever.
Just take a look at the 4890 spec.
Check my System Specs, I know the spec of the 4890 quite well thanks.:)
I also know where the bus argument is drawn from... it's source.:p
 
No matter what, the card is cheap to make.

Like a 4770, and it got higher bandwidth than 4770.
 
dumn it is very close to 4870 performance
 
Complaints about the bus are practically always in comparison to nv's 512-bit bus. As you see, it's a hot favourite:

It's clear you don't. You just quoted two posts that have nothing to do with Nvidia or 512 bit, from two members that use Ati cards. If you know your card you should know that it has the exact same specs as the HD5770 except for the fact that it has much higher mem bandwidth and it should just take you a look at the benchmarks to see that the HD5770 is signficantly slower in (not so memory hungry) 3Dmark. The argument about Nvidia's 512 bit vs Ati's 256 bit is absolutely pointless here, since both Ati cards are using the same GDDR5 memory and thus half the bus width automatically means half the bandwidth.

Not to mention it's been you and only you who has brought that argument to the table. I suggest you clean up your paranoia. No one's saying this is a bad card or an slow card, but that it's been bottlenecked by the memory is almost unquestionable.

But, all in all, pron inspector has probably better replied to your argument by saying:

Whatever.
 
Theoretically, a card with half the bus width but double the memory speed should offer the same performance as a card with double the bus width and half the memory speed.

I.e. 128-bit + GDDR5 is theoretically equal to 256-bit GDDR5 in terms of bandwith, and as long as the GPU core is able to access sufficient bandwith, the 128-bit bus limitation won't really matter.

However, this can be said of cards with stream processors less than 800 only. The second you start putting 1200 shaders into a 128-bit card, you're creating a bottleneck that cannot be removed even if you paired GDDR6 with it.
 
less than I expected, :ohwell:
 
It's clear you don't.
Oh, ya, okay you've convinced me; I don't know my own card.:laugh:
While we're at it, yeah, I'm saying the people complaining about bus are using nVidias.
And don't forget that I'm paranoid and have a gun under my pillow waiting for you to walk in my door.:roll:

Read between the lines of what I'm saying a bit before you go off in a rant.:p
...where the...argument is drawn from... it's source.:p

but look at the memory bandwith , it's not much better than a 3870 :laugh:

The ATI Radeon HD 5770 is expected to be released on October 13th for $159. This DX11 card features 800 stream processors, a 850MHz core, 1GB GDDR5 memory at 4.8GHz, 1.36 teraFLOPS computing power, 128-bit memory bus, 76.8GB/s memory bandwidth, 18W idle power consumption and 108W load power consumption.

that makes it not much better than a than a 4870 , i thought these was supposed to beat the 4870 and match the 4890 or even beat it ?

Argh to the first chart. :confused: I'm colorblind goddammit! :mad:

Ninja: It must be my brains, I can see it right for few seconds, then the colors start to fade and dance in my eyes, changing places and that sort of things. Drives me maaadd!

That is why I used the qualifier, almost.

The three I have and modded are 4890 comparable. I am tired of the hassles with them and that's why I'm going 4870.

This card is going to 1up the HD4890 big time.


Big handicap that has been noticed is that images of HD5770 show a single Crossfire finger which will limit crossfire configuration to a max of 2 HD5770s.

A multi card crossfire "T" type of crossfire bridge rated for higher bandwidth could possibly overcome this handicap.

For now it looks like more than 2 HD5770s in Crossfire will not be possible with standard crossfire bridge.

:(

I really wanted to see some quad fire HD5770 reviews. The benchmarks with 4 HD5770s would be insane.

why would you want 4 5770's ? , you might as well pay for 2 of the 5850's which would proberly cost less

Not sure yet. Just pointing out that it appears that the HD5770 has been deliberately crippled for multi GPU crossfire configurations.

2 HD5850s at $269.99 each is around $540.
4 HD5770s at $169.99 is around $680.

I have no idea how these 2 configurations compare in performance but it would have been cool to be able to know. With the single finger for the HD5770 it will be hard to ever know. It's crippled.

I would have liked to have seen some quadfire performance reviews for the HD5770 like this one that was done for the HD4770: http://www.tweakpc.de/hardware/test...i_quad_crossfire/s05.php?benchmark=3dmv&lang=

Where? Both 5770 & 5750 have dual CrossFire connectors on the reference board. You might see a cheaper board (non-reference) by Sapphire or TUL down the road with one CrossFire connector, but all the boards at launch that I know of will have dual connectors.

Thanks. Forget about what I posted. A misunderstanding due to lack of information.
