Saw this early this morning: http://www.guru3d.com/article/radeon-hd-4750-rv740-review-preview-test/

The card performs near the HD4850 and is supposed to cost less than $100. Pretty nice...

More importantly, looks like this is the world's first 40nm GPU to see the light of day. :eek:

Here's the digg link if you're interested.

I think this could be a really popular card for the mainstream audience. It could even work well in HTPC's thanks to that fan on there.. looks pretty quiet (don't know if that will end up as the reference design since it is a super early sample).
 
I wish they'd at least given a non-scientific estimate of power consumption... Even without power-saving, you can at least say "It never exceeded xx watts, so expect the finished product to be similar."
The 6-pin connector doesn't instill hope... :(

Still, looks good from a performance standpoint! As long as it's under 90W, it'll be okay. Maybe they can release a lower-clocked, 70W version (4730?) that won't need the plug.
 
thank you so much for that link, you've just helped me out tremendously;) i was going to pick up a 4830 but now that i've seen this is evident that the RV740 could cause some serious price/performance changes in the market after its released. waiting out for sure.

Yeah me too. I would love to see this thing be bus-powered. They mention that they weren't under NDA so they just must not have run the power consumption tests

ha no problem. I am actually thinking about this card myself now... I was going to go with the HD4650 or 4670 in my HTPC build coming up... but now this thing is.. wow

(edits: i cannot type, sorry)
 
100 dollars MSRP base, for that performance is smoking.

This willr eally apply even more pressure on nvidia's 9800gt/gt240 cards, since it appears to be safely beating them in most things.

Now with this engineering sample in house we feel it's not fair to include numbers on heat, noise and power consumption. The specs are not yet 100% finalized, neither was power management and as such it would be unfair to include. So we'll hop straight onwards to a photo-shoot and then will fire up a couple of benchmarks to see where the product is going to position itself.

There were reports of some pretty bad power leakage with the 40nm process at TSMC so this might be a result of that. Also could just be that this is an engineering sample and the extra connector is there to take low power supply out of the equation if it crashes.

I wish they had included a picture of the naked die without the heatsink to see just how small this thing has gotten on 40nm, guess I'll have to wait a little while longer for my GPU pr0n.

The numbers it put up are pretty exciting. NVidia really has no competition for AMD in this pricing bracket now and AMD is definitely taking advantage in any way it can.
 
yueah seriously. AMD has got themselves in a picture perfect spot. nvidia has no market there, and hopefully ati's new top end 40nm card is able to compete with the 285. i have a feeling it might actually oust it because AMD is actually doing tweaks to the 40nm die shrink from the 55nm. on top of the tweaks, and added shaders, and everything else, the clocks speeds can go up ON TOP of all those additions!

Nvidia's die shrink to 55nm yielded absolutely NO INCREASES with the exception of less heat, and a mere few watts less power consumption, which allowed them to raise the clock speeds up a bit to get another 10-20% more performance than the GTX280.
 
the shrink from a 65 to 55 was an optical shrink, so returns were minor, the 40nm is a whole new process.

Hopefully the voltage leakage issues will be resolved before the dx11 parts go into production.
 
Pretty cool of them to come out with something like this, although it also makes me wonder what they're going to do with the 4830 now that they have another product planned that's wedged in.

drop the price and make some profit while creating another section of the market for people to buy parts from. more choices, more killing nvidia :p
 
this card will absolutely crush Nvidia in that market. Basically 8800GTX performance for < $100. A 4750X2 is giong to be killer!

I think the lowest I have seen the 4830 was $67 AR. What do you guys think will be the lowest we will see a new 4830 for? $55 AR w free shipping? :D
 
The 4830 might be discontinued, and the 4850 might almost be too, it is rather close to both in performance.

They might have 2 versions, one clocked at around 600-650 and say a higher clocked one to replace the 4850 completely, while keeping 128-bit width and gddr5.

With the release of the R790 chip, with unknown stats in a few months, it would be a refresh with bumped clock speeds to hold off until the dx11 parts
 
HD 4870 1Gb - $175-200
HD 4870 512 - $150-175
HD 4850 - $125-$140
HD 4750 - $100
HD 4830 - $70 -80

Any ideas?

i could see that, but then people are start going to complaining about ATi's value deflating.
 
I would call the R740 not a 4750, but instead 4840, since it slots in best at that point.
 
Actually, I remember when the 4850 and 4870 were released, and people here were cheering, simply because of the massive drop in prices for performance level gaming cards, the 9800gtx dropped 100 dollars overnight, and the gtx26/280 dropped quickly over the next month.

Only people who were grumpy were those who paid for the gtx280 before the new ati cards forced the major price drops

most people other than enthusiasts can care less about that.

besides, thats technology for you. i paid about $290 for my 8800GT a little over a year ago.

the same friggen card was worth $100 in less than a year. now its worth about $200 less than when i bought it.

no, i don't have that card anymore. lol.

that might be true

Does it make sense to make a 40nm GDDR3 card with 256 bit memory interface? Of course they will keep the GDDR5 cards but is a wider memory bus (and 160 more stream units) worth making using GDDR3?
 
Now what you'll notice is throughout the scope of tests we run is that the 4830 and RV740 are pretty darn close to each other in terms of performance. In the majority of games the RV740 is in fact slightly faster, nearly humping the 4850.

lol
 
awesome card, may be just the thing to replace the passive 7950GT in my LC16 media-pc case.

Not really, a thinner bus, with 128 bit, and clocked gddr5, is the same speed as a 256bit bus, and gddr3, roughly. The real issue is that 256 PCB are more expensive to make, gddr5 will be continually dropping in price, and at 40nm you get rather close to being pad limited.

Probably the only reason the 4850 uses gddr3 instead of gddr5, was the question of availability in summer, now that has been resolved, any mid range card will just use gddr5, and lower cards will likely instead use higher speed ddr3.

I wonder, given the size of the chip maybe it wasn't the board cost (256 bits isn't that bad) but it was actually pad limited?
 
With the perforance range, there is little reason to go to a 256 bit bus, and gddr5, with a chip that slots between a 4850 and a 4830. wider bus and gddr5 makes sense for 4870 or higher processor speed of coarse.

a 192bit bus might work in that range, but saving even a few dollars when dealing with lower margin products in the sub 100 dollar range, is a good thing. Remember, this chip will compete with the 9800gt and it's derivities, which are larger chips, and a wider bus, so any cost savings is good and important
 
These cards will be a killing on Nvidia's margins though. I bet with some good cooling, these things can OC like monsters at 40nm

What? People like cheaper cards. If you're referring to people who sell their old cards and buy new ones, well, they're just going to have to live with it.

I remember the x800xl days where that was a new process solution. Unfortunately the process wasn't mature and the card's cpu never overclocked very well.
 
Since the GPU is built on a new process, shouldn't they up the generation number? Like 4930 or 5670.

New generation number implies superior performance. This is a budget card nearly as good as the 4850, not better than the 4850.
 
Wow, a 8800GT~GTX performance for less than 99$. Nice jon ATI.
And this is only the begenning of 40nm too...I can't wait for the high end 40nm stuff.

nVidia needs to stop renaming the same ol' cards over and over and dish out something or else they're gonna lose a lot of share when this card hits the shelves

they have no new tech. its their fault theyre losing... ati's 4800 cards creamed them, and i dont know if you guys remember but nvidia was cpnstantly bashing ATI to the press...

so much for that.
 
Is that really the reference design (the cooler) ?
Now there's a new look! I was expecting the same flat thing with a metal plate attached to it, you know the one.
