ATI Radeon HD 4650 and 4670 Benchmark Results

http://img257.imageshack.us/img257/2...board02dt6.jpg

Chinese based website IT168 got their hands on with RV730, the upcoming HD 4670/4650. Initial test shows that HD 4670 is really close to HD 3850 512MB，which is only $100 in newegg. The core RV730 is a 55mm chip, running at 600MHz/750MHz(4650/4670), memory @ 700MHz/1000MHz(4650/4670), shader count is 320, the same with RV670. But memory interface is only 128bit, which sounds very low end… In benchmarks 3DMark Vantage shows HD 4670 still can not easily catches up with HD 3850 512MB. But in actual games like HL2EP2 and COD4, the card performs very well, only a few FPS less than 3850. (source)

You can wade through the 20+ pages in Chinese here ... or save some time, all benchmark results in one chart:

Very interesting, definatly appears that it has a much better GPU core, which I'm not suprised by since it does have 2x the TMU of the HD3850 but it appears to stall out @ higher resolutions because it lacks enough bandwith to keep up past 1600/1200

If AMD was smart they'd have a DDR5 version as there's a good chance that would match / beat the 9600GT/8800GT

Nice. Those RV730 optimizations over RV670 must be quite something--it basically matches a 3850 512 but has 128-bit memory. ATI seriously needs to upgrade that--256-bit for midrange, 512-bit for highend.

RV770s all had 256bit controllers you're thinking of the initial R600s. Either way you're absolutely correct, just a smidge more bandwidth and they could be utterly devastating to nVidia.

I've uttered those comments before. ^^

Anyway AMD will wait until Q1 2009 to release the ultimate midrange card. RV740. Probably even more shaders on 40nm, but GDDR5 is a definite.

As is now, this gives the 9500GT absolutely no room to live in the $50+ market. It's gonna go below, which is kinda sad.

what is this "8" on rv635, rv730 and 16 on rv670? ROPs?
only 8 ROPs?

It was good until I realized that it wasn't compared to the 4850, but the 3850.

You do realize the card is less than $100 right?

for the HD 4670 to be competitive its price should be $100 or less, with the HD 4550 coming it at $50-60 not much room left in the $50-100 price bracket as the HD 4650 has to fit in there somewhere too...

HD4650- $70-$80
HD4670- $90-$100

This is MSRP. We haven't talked about mail in rebates and the like yet. They'll phase out 3850 (discontinued) so no big harm. Of course pricing should be right, though.

yup; an interesting price point, if they can pull of a 3D card which can run most games HQ at 1600x1200 (without AA) this will be a very popular product

man if they only had a 256bit bus! it's so close. the sad thing is that the 9600gt is only $10-$20 more and beats the 3870 let alone the 4670. but if they move the price down to the $70 range it would be a smash hit! Crysis at 1680x1050 on medium settings and 39FPS for $70 would be sweet!

lets hope rv740 fixed those problems (imo the 128bit bus will stay, and probably will in the next couple years)

Seems that they are smarter than you at least. Guess why? :p: It's called HD4850. Beisdes GDDR5 won't fit to this card really as it is intended to be cheap as hell. Though, very welcomefor Palit etc. to create their own cards. Sonic model with GDDR5.. :drool:

Oh, if it wherent that bandwith limited. it would have beaten the 3850 easily... i bet it clocks good too.

Me thinks if it were running on a 256bit bus the 4650 would of beat the 3850, and the 4670 would of edged out the 3870, as they would essentially be the same cards. I'll think we'll very likely see GDDR4 versions of the cards, kinda like there were DDR4 versions of the 2600xt that performed slightly better than the DDR3 versions. Granted if these things have any OCing head room, that could change the picture a bit.

The other big question is, are they hybrid crossfire capable?

As soon as a GDDR5 version is cheap enough, I'm sure AMD will make one. Otherwise, I have no clue why they would stick to 128-bit controller.

wow, the 4670 looks great to make a cheap TF2 lan box

the 4670 is still enough for all modern games (cept a certain beach setting simulator)

It doesnt need external power!!

Thats huge, I am also pretty sure thats the reason they didnt go 256bit.

They don't OC well. TDP is near (if not) 70W and PCIe bus gives out 75W. ...5W can be eaten by higher RPM(catalyst profile mod/rivatuner etc.) cooler, for example.

AFAIK Only x4xx series cards support Hybrid CF.

Actually my main concern is the overclocking. Will there be non ref PCB cards with power connectors and/or GDDR5? If not, then there is no overclocking this card, let alone OC'ing with vMods...

But these are not aimed at you, any guy with a good psu will get a similar priced HD3850/8800gs.These are for the dells, hp's, fujitsu's etc.

This card is class imo, its way ahead of cards that dont need external power like this.

It kills its nearest challenger the 9500gt and can play COD4 on Very High @ 1280 x 1024 at 50fps, Crysis on medium the same.Anyone that owns a 225watt Dell with low core 2 duo can now game at decent settings.The industry needs cards like this and with GTA 4 and Warhead out soon this card could do very well.

These cards are aimed at ME, as I will not buy a card which costs more than 100 euros or has a power connector. I will rather have very good deal wiuth mid range hardware than having to pay all I got for high end card.

Besides, Palit introduced GDDR3 version of 7300GT, as well as of 7600GT. Same cards were meant for OEMs and low budget systems. I wouldn't be surprised if they introduced GDDR4/5 version of this card, especially when this card really begs for bandwidth.

No they won't, GDDR 4 and GDDR5 is to expensive for low-end cards, even for mainstream models.

@ Calmatory : Gddr5 needs alot more power, they wont be able to get that card to work without a pci e cable imo.

Any place you now in the EU that are selling these?

and tread on the toes of the 4850

It OCs to 875 on stock. Happy?

As has already been said, GDDR4 already appeared on the 2600XT so it could yet appear on a 46x0.

I'd like to see how it compares to the 9600GSO (8800GS), just for a comparison since they're not in the same pricerange.

I think you are mistaken.

GDDR-5 Microcircuits can be produced with the use of four-layer design, whereas GDDR-3 required six-layer design. Of course this reduces the prime cost . In the energy consumption plan GDDR-5 win over GDDR-3 by about 30%. To autumn Qimonda engineers will reduce the working GDDR-5 voltage from 1.2 to 1.0 v which also favorably will affect the energy efficiency . The density of GDDR-5 microcircuits will also allow to create video cards with large memory capacity. Qimonda actively increases the GDDR5 memory production volumes . . ........

http://xtreview.com/addcomment-id-57...-vs-GDDR5.html

for every generation they try to lower the power/energy consumption.

ATI should just hurry their game and make a laptop version of the RV730.

An RV730 + 512MB GDDR5 lappie would be sweet :yepp:

Some of you guys should do a little research before you go on about power consumption figures: link
It actually draws less than a 3650 under load, which is around 40w, and 35w less than 3850, which is around 60-70w 3850 power draw@xbitlabs
And as already mentioned, GGDR5 draws about 30% less power than GDDR3.
All in all it seems like a damn efficient chip! A laptop version with GDDR5 could prove to be very good as well, as soon as they can ramp up GGDR5 production.

Shouldnt be to hard to solder on a external powersupply connector... no? For thoose who wants some cheap OC fun.

Excellent card for anyone using 22" displays and smaller who wants to be able to do some light/medium gaming
Seems perfect for a family computer build

if the pcb has solder points, then yes.

But what a REAL GODSEND if the card can clock well and has so low TDP. :O

Going to pick mine as soon as they arrive in Europe.

This is an awsome card. Some people aren't seeing the advancement here. You start from the big and energy hungry fiasco named 2900XT. It was 512 bit and needed two 6-pin conectors. Then came the 38x0 wich were very decent 256 bit video cards, that needed one 6-pin power conector, and had the same performance than 2900XT. Now an 128 bit card, that don't need any power conector, is close to 3850 speed, at the same 55nm process! And an GDDR5 version will probably drive it to 2900XT's performance level or above! With 3~4 times less energy consumption, 3~4 times lower price and 4 times smaller buss. All this in less than an year and a half. Admitedly, the starting point was very low, but nonetheless.

I'm with Calmatory. The 4650 should have overclock headroom, and will be cheaper. Aside from crisis, where it's performance is strangely absmall (probably an early driver bug), it seems an good get for an casual 19" low budget gammer like me.

any news on the supposed HD 4750 with 480SP's and 192-bit interface...

small die example 3470 which has gddr3 instead of ddr2(3450), 64 bit interface. (also the lowest card with crossfire connectors.)

I have two they are very over clock able. (HA06 780G 9550 phenom in crossfire wtih 3470's)

Rivatuner can take them up to 1,000mhz core & memory 10-15C more heat but they're passively cooled.

this makes me wonder how a 2900 xt would've preformed with gddr5 lol

as it says on techpowerup

gddr5 on 256 bit is = to gddr3 on 512 bit

gddr5 on 128 bit is = to gddr3 on 256 bit

gddr5 on 64 bit would be = to gddr3 on 128 bit.

and so on half is needed when gddr5 is used.
