Another Radeon HD 4770 Pictured, Tested

btarunr · Apr 22, 2009, 01:56 PM

As we head towards the launch of AMD's newest GPU, the ATI Radeon HD 4770, things certainly seem to be looking good from what we have seen of the sub-$100 accelerator so far. After the recent exposé of the HIS HD 4770, it's time now for the one from another AIB.

The card features an identical overall design to the one from HIS, indicating that the cooler is a standard reference design, not what we had seen from the company presentation of HD 4770, showing a rather visually-appealing cooler. The card features 512 MB of GDDR5 memory across a 128-bit interface, 640 stream processors, and DirectX 10.1 compliance. Taiwanese website CoolPC put the card through a round of 3DMark06, 3DMark Vantage, and FurMark. The testbed consisted of an Intel Core 2 Quad Q9550 processor and 4 GB of DDR2-800 memory. The card secured 12,042 points at 3DMark06, and P7408 at 3DMark Vantage. After 350 seconds of FurMark stability test, the GPU temperatures were tipping 72 degrees Celsius, with the fan running at 42% speed. Here's one card to look out for.

Many Thanks to Duncan1 for sending this in.

I dont like that sticker* fin on the heatsink. Looks better bare heatsink in my opinion.

EDIT: Heh, spelling. I mean that flat thing on top. Its ugly.

newtekie1 · Apr 22, 2009, 02:04 PM

I hope one of the manufacturers put a rear exhausting fan on this, because the stock cooler is butt ugly.

Looks like I have something to look forward to, probably going to upgrade my HD4670.

oli_ramsay · Apr 22, 2009, 02:11 PM

I wish they showed it's OC capabilities. There must be huge OC potential with a 40nm chip and maybe a vmod

DrPepper · Apr 22, 2009, 02:21 PM

God that heatsink is ugly.

MRCL · Apr 22, 2009, 02:22 PM

I'm one more to find that fan thing fugly. But seems to be a nice card. And sub 100$, would be an ideal backup card.

Polarman · Apr 22, 2009, 03:04 PM

Those GPU-Z Sensor tab look dubious. 2000mhz gpu core !?

DaMulta · Apr 22, 2009, 03:13 PM

I'm sold now!

Im getting 4 of these!

It ll probably get fixed on the next GPUZ release.
Nice card but i d rather buy a 4830 for 90 euros here...
I dont like the 128 bit bus...40nm though IDK...

128bit bus is negated by the GDDR5 which runs at QDR speeds.

128 bit bus with GDDR5 = 256 bit bus with GDDR3, because of the GDDR5 quad data rate VS the GDDR 3 double data rate.

Ok thats good.But what about OCing the ram?It operates at lower voltages so maybe its more fragile to overvoltage.Time will tell though as we might start getting vmods and results!

Since my card is a 4670, i can't answer that question: ask dudes with 4870 / 4890 cards since those have GDDR5.

cdawall · Apr 22, 2009, 04:20 PM

now were is the 4770X2

The chips in use are marked Qimonda "IDGV1G-05A1F1C-40X", these chips are spec'd by Qimonda to run at 1000 MHz (and 4 GT/s per pin). ATI is running them at 800 MHz. So you already have a 25% headroom there.

you have to look from the ground to see it;even at transparent panels you don't see it

my point if a cooler done his job =good

btw this card beat my 3870

1Kurgan1 · Apr 22, 2009, 05:05 PM

Is it just me, or is this thing as fast as a 4870?

Imsochobo · Apr 22, 2009, 05:14 PM

Expect oc versions to be like a 4850.

This would be up and down on the 4830, it got less bandwidth, the memory modules are rated at 1000 mhz, which is actually lowest ive seen GDDR5 rated as.

as an effect, theese push same bandwidth and speed like an simular videocard(4830) with crazy overclocks and 1000 mhz memory on 256 bit memory bus.

It isnt as fast as a 4870 by a long shot, 4870 got twice the memory bandwidht, is approx 30-40% faster, depending on game, settings and resolution.
due to memory bandwidth, this wouldnt allow high AA levels, but would allow AA levels up to 8X and 12X in many of new titles at a 1680x1050.

This is a very very popular monitor resolution.
4850 is still faster due to more shaders, higher memory performance, by default.

Expect to see almost neck to neck results when overclocked to 1ghz memory, this would be an 65 gb/sec memory bandwidth versus an 62.8 gb on 4850, 4850 may still have more headroom on gpu overclock.
*Remember, 4770 runs a high default core clock, and 640 shaders versus 800 on 4850, 4850 got a good headroom, closing to 4870 at 720 mhz is max ive done on relativly stock cooler, voltage.
Still, best card there is at sub 99$, ati will harvest some serious cash with this card, due to 128 bit design is cheap, licence money for 40 NM may be expensive, but should pay off due to cheap design.

I'm expecting much of this card, and the downfall of GTS 240 250 9800 GT 9600 GT and the whole G8x g9x series cause of this card.

My thought:
Killer card for the 1680x1050 and lower gaming, i'd reccon 4870 and alike for the 1920x1200, if you like high settings, for those who do not like it, i really think 4850 would be best killer for mainstream card at 1920x1200

KainXS · Apr 22, 2009, 05:20 PM

I'm actually very dissapointed if that GPU-Z shot is right, it seems alot slower than it was said to be, . . . . only 8 rops T.T

No man, the HD4770 is a little more slower than HD4850.

KainXS · Apr 22, 2009, 05:27 PM

with only 8 rops and 640 shaders I can't see how this card will even outperform a HD4830 with 16 rops and 640 shaders, . . . even if it does have GDDR5 . . . on a 128bit bus

It already did. Check Guru3D's preview.

It isnt as fast as a 4870 by a long shot, 4870 got twice the memory bandwidht, is approx 30-40% faster, depending on game, settings and resolution. due to memory bandwidth, this wouldnt allow high AA levels, but would allow AA levels up to 8X and 12X in many of new titles at a 1680x1050. This is a very very popular monitor resolution. 4850 is still faster due to more shaders, higher memory performance, by default. Expect to see almost neck to neck results when overclocked to 1ghz memory, this would be an 65 gb/sec memory bandwidth versus an 62.8 gb on 4850, 4850 may still have more headroom on gpu overclock. *Remember, 4770 runs a high default core clock, and 640 shaders versus 800 on 4850, 4850 got a good headroom, closing to 4870 at 720 mhz is max ive done on relativly stock cooler, voltage. Still, best card there is at sub 99$, ati will harvest some serious cash with this card, due to 128 bit design is cheap, licence money for 40 NM may be expensive, but should pay off due to cheap design. I'm expecting much of this card, and the downfall of GTS 240 250 9800 GT 9600 GT and the whole G8x g9x series cause of this card. My thought: Killer card for the 1680x1050 and lower gaming, i'd reccon 4870 and alike for the 1920x1200, if you like high settings, for those who do not like it, i really think 4850 would be best killer for mainstream card at 1920x1200 . __________________
