For instance, alot of people claimed R600 was faster than G80 especially in DX10. Cards look good on paper, so lets see what it can do in real life.

agreed. if the 4850 does well with WIC 19x12 rez with 4xaa or at lest 2xaa ill sell my toxic 3870 for it.

im guessing that the 4850 will have the rear audio hdmi out like the 3870?

this is key to me. ive been watching HD movies via a 25ft hdmi cable to my 42" plasma and it has been phenomenal with the audio included until i can afford a full-blown home theatre setup.

Are you planning on using driver CD or 8.6 Betas?

They're *supposed* to include support for the 48xx series. I'm assuming 8.6 final will be ready by launch?

 

[zod96]

Aw good question, I'll probably bench with the 8.6 beta's

you can bench the crysis demo, too.

Great idea Bryan, then I looked at the file size. Wow. If other benchies warrant it I'll download that hog. I only get 80k/sec..

download it from nvidia's website, it gets almost 1m/sec there.

do a few things other than 3dmark 06. amd supposedly has actually focused on game performance instead of 3dmark this time...though vantage is supposed to run much better.

I've only got 1 game darn it :-( BF2 is their any type of game I can download that has a free benchmarking utility built into it? Does the crysis demo have one?

Crysis (and the demo) has a batch file that launches an in game benchmark based on the first level of the game (island). It's in the folder where Crysis is installed.

Maybe I'll download it while at work tomorrow. Let's see if Big Brother notices...

I would not imagine a sub $200 being all that much faster than a 9800GTX. So that review may be accurate.

Although I would wait until true reviews come out before jumping the gun on anything.

you might want to start downloading it tonight. it's nearly 2gb for the demo

This thread has some pics of ATI slides. It shows the 4870 due on July 8th.

The latest info shows the 4870 coming on July 8th, which could mean a June 25th paper launch. So that would not be very good at all.

doesn't show the cpu speed for the 8800gt. for the 4850 they had it @ 3.2ghz. I highly doubt anyone at xtremesystems has a quad running less than 3.6....

 

[dreshyne2g]

It's true ordered mine yesterday. It will be delivered on wednesday.

Who cares about reviews? Extelleron said AMD performance slides are to be trusted, who can argue with that logic?

well, consider that the 4870 is a 4850 only with GDDR5 ram instead of GDDR3... and the delays in aquiring GDDR5... I expect price hikes on the 4870...

if the 4870x2 can really share the ram, then maybe we wouldn't be seeing any 4870s for a while due to ram amounts, and just 4870x2 GDDR5

if 4870 is available at the rumored $299 then it will be VERY good. gddr5 on that card is going to make a world of difference at high resolutions imho. the only question is when will it be available? of course, we could ask the same of 280 and 260 since nvidia doesn't seem to be exactly flooding the market with them...if 4850 is the amazon then 280/260 is my sprinkler.

with GDDR5 + 256bit bus it should have the same bandwidth as nvidia's 512bit bus + GDDR3...

The only difference is that nvidia has the option to make a GDDR5 + 512bit bus with extreme ease.

taltamir, you really need to get off the 512 bit + gddr5 kick. gt200 has not gotten nearly as much kick from being 512 bit as I expected. throwing in gddr5 would be a waste on current games. maybe in a few years, but right now you would add ++++ cost for + performance.

it is not THAT expensive. AMD will be selling the 1GB of GDDR5 model for only 100$ more then the 1GB GDDR3.
650 -> 750$ isn't too bad, especially because it might come in handy in 2560x1600 max everything with tri-sli. Will it be earth shattering improvement? no. But it should give a minor improvement with existing technology and no chip rework.

Plus there is the all mighty marketing. I am sure some people would pay 200$ more to have it just because the numbers are higher, even if it gives no performance benefit at all.

That and GDDR5 takes 2/3 the electricity (and thus generates less heat), which should improve the thermals of the whole card, probably allowing it to OC higher. (to OC the core I mean)

GDDR5 implementation is different, it has got 2 DQ parallel links which provides high bandwidth unlike GDDR3.

 

[OCGuy]

Wow 4850 < = 8800GT? Way to innovate!

 

[unr3al]

I don't think the HD4850 will be slower than the 8800GT in any way. If the 3DMarks we saw earlier are correct then it beats it by around 2000 points. Even for real-world gaming thats a huge difference. I'm waiting for an actual comparison review from here or toms...

 

[unr3al]

And speaking of the June 18th release date, wasn't that delayed to the 23rd?

I think it was the 25th...not sure...anyways does anybody know when the reviews will come out? I bought a VisionTek 3870 OC edition from BB a couple weeks ago when they had a big sale for $120 after coupon. If the 4850 turns out good performance for the $200 it will be selling for, I'll take my 3870 back to BB and get a refund and buy a 4850.

I wonder if we'll see any 4850x2 down the line....

More than likely. I just saw an article yesterday that mentioned this. Will either come around the time of the 4870X2 or a little after I would imagine.

it will be quite an interesting lineup if the rumors hold true about performance of the chips and the x2 cards improvements.

4850 ~$200
4870 ~$300
4850x2 ~$400
4870x2 ~$550
