ATI Radeon HD 4770 Specs

[RazberyBandit]

The only card currently known to be on it's way out is the 4830. Anything else is rumor mill speculation. I don't think we'll know exactly what AMD/ATI has up their sleeves until after the release of the 4770 itself.

And boudy, from the publications we've seen so far, the 4770 is set to eclipse the 8800/9800GT performance and will likely encroach on 9800GTX+/GTS250 performance. As far as match or surpass them, we'll have to wait and see, but I doubt the surpassing part... That's the 4850's job.

It was a bit of sarcasm more than anything. I doubt (but one never knows until a decent amount of unbiased testing is done) that it will surpass the HD 4830 by much or at all. As such it won't be competing with the GTS 250, which is the HD 4850's class.

I'm sure it will be a great card for its niche from everything I've read. Think along the lines of X800 XL, 6600 GT or 9600 GT when they first came out.

No it wont surpass the GTS 250 performance-wise, but price/performance-wise, you can bet that the 4770 will give it a run for its money.

So does that mean they'll doing away with the HD 4850 too? Because the GTS 250 already competes with it and oftentimes wins

It all depends on what this card can actually do, and then Nvidia's reaction.
But to be honest, I just cant see a GDDR3 card right in the middle of 2 GDDR5 cards.............I just cant.....it seems weird to me :lol:

If this card's performance ends up in the middle of the 4850 and 4830 though, how the heck is Nvidia going to compete with that? Are they just going to rebrand the 9800GTs?

 

[RazberyBandit]

Well, considering the 4770 is using 128-bit interface w/ GDDR5, it still has less memory bandwidth than the 4850 with it's 256-bit interface and GDDR3. It's not a huge difference, but that difference is enough to make the 4850 configuration the superior of the two.

Hasn't nVIDIA already rebranded them as the GTS1xx-series cards? And does anyone actually know what GPU is performing the graphics of the nForce 980a northbridge?

[RazberyBandit]

Yeah, but what about the 100 series? Are they G80's or G92's?

G80s haven't been used since summer 07 I believe, ever since hte 8800 GTS 512 and 8800 GT came out.

 

[boudy]

Yeah, but what about the 100 series? Are they G80's or G92's?

I have heard a lot of rumors.
Here is another on what is going to happen:

G92 cards will be known as NVIDIA GeForce GTS 150, G94 should be offered as NVIDIA GeForce GT 130 and G96 will be transformed into NVIDIA GeForce GT 120

It is really confusing me, but I guess we will just have to wait and see.

 

[L1qu1d]

Theres nothing to wait though, Nvidia canceled those cards. They aren't renaming them last I heard.

 

[r_manic]

Many sites will, just like they did with the pre-release 4890s and GTX275s. We saw cards from the partners, then. But, didn't ATI already pass around a few of their "home-grown" or in-house reference boards?

I'm honestly not sure. I think most of the info being discussed here originated from a presentation slide that was leaked or made public. It's probable some companies already have the actual hardware, and are under embargo not to reveal anything until launch date?

 

[RazberyBandit]

I think it may have been Guru3D who got an engineering sample...

Yup. Just checked. http://www.guru3d.com/article/radeon-hd-4750-rv740-review-preview-test/1

that rv 4750 not 4770

 

[L1qu1d]

but in far cry 2 it almost matches the 4850 and this is the 4750 not the 4770 lol!

K now I know for sure the 4770 is going to wreck the 4850 and pose problems for the 4870

 

[r_manic]

Which could be a good thing for ATI (and a bad thing for 4870 users), since it will drive sales of a new product? Or will that rumored $100 price point hurt 'em in the end?

 

[JAYDEEJOHN]

Check those slides again. The usage of AA is all over the place in them. As you know, the G9x series wasnt great with AA, so its slightly cooked in ATIs favor, so those %'s we see in the slides are a lil tilted.
Remember, hope for the best, expect the worst

 

[L1qu1d]

why is this a good thing for ati?

They are killing their 2 cards lol, casting out the 4850 and the 4870 out....not only that but the it wouldn't make sense with the names

4770 > 4850?
huh?

4750 ~ 4850
about with real drivers, we might see it.

 

[JAYDEEJOHN]

Being that the arch is shifted around a bit, and the clocks are higher, it wouldnt surprise me , in a few games to be = to a 4850, at 99$

 

[L1qu1d]

remember like you said, the drivers are beta, the 4850 reached its potential, the 4750 still has to grow, at 3-5 frames difference, I think its very much achevable to eithe mathc it or kick it off.

Not only that remember we're talkin about the 4750 not the 4770. Last I checked the 4770 is 100, what is the 4750?

 

[L1qu1d]

or was the 4750 from the review what we call now the 4770? I might have misread, but even so, it pretty much killed its older brother the 4850.

I wonder what high optimized drivers can do, I mean 5% is pretty given, but some cases 10-15% is possible right jaydee?

 

[JAYDEEJOHN]

Cant remember price quotes. 79$?

that rv 4750 not 4770

Wrong... From the article:

We are going to bring you guys a nice little sneak preview of what ATI is working on. Let me clearly state, nothing in this review is finalized or can be seen as a concluding fact, the specifications (clock frequencies) and configurations might change for all we know. We are testing an early engineering sample here. It will however be a pretty good assessment of what ATI is going to release somewhere in April.

You guys ready? Let's meet the RV740, and though we don't know it's real name just yet, allow us to call this product the Radeon HD 4750 for the ease of understanding, product placement and well... the sake of the most logical name for this product, mmhh okay? Next page please.

4750 is what they called it, nothing at all official from AMD/ATI. It could very well be the 4770 engineering sample, and based on the benchmarks in the review, it probably is. All we know for certain is it used the exact same components listed in the 4770 pre-release information: RV740 core w/ 128-bit GDDR5.

 

[L1qu1d]

yes i said in a post after that it might be the 4770 renamed at the time. Thats why I said I might have misread.

 

[RazberyBandit]

Yeah... just re-read your second post and saw you say that... Sorry mate.

 

[L1qu1d]

no worries, I'm a little cranky 2day anyways, got a CPS exam 2morrow, not that ready for it
