ATI Radeon HD 4000 Series discussion

Don't forget, if you live in a state where best buy has stores, they will charge you tax. 305 + 8 in shipping is $313. 299 + 7% sales tax is $319. So if you live in a state without best buy (are there any?) you win.

OH Yeah ...VisionTek has a lifetime replacement warrenty

Seems people are getting to 900Mhz on GPU (some people) and 1200 on Mem on air (albeit not stock air cooling but a S1). Wonder how that benches... thats nearly a 1/3rd more power. Might have to get these cards soon since it makes a good project. Long live AMD.

mine arnt doing badly now i have the hsf working at propper speeds....
i'm just at the stage where i'm trying to make the new bios i've created make the core speeds stick....
i posted this screen shot in my 4870 thread but i'll post it here aswell....

by the way, i've never seen this bench score so high, 3000 points higher than my 3870's and 2900's.....

this aussie e-tailer has a 4870 1gb listed,no price though but dated for JULY 8TH!

I ran crossfire on my P45, 3dmark 06 @ 1920x1200 resolution, i got 19,400 3dmarks, cpu at 3.8ghz, memory at very low 1140mhz ddr3 cas7, new memory coming tommorow, and this is with single channel 1 dimm, p45 crossfire is amazing..........played some TF2, frames went well into 150-250 area 1920x1200 8xaa 16xaf..........all i can say is ATI is back!!!!!

[disruptfam]

p45 crossfire is amazing?!?

[iTravis]

Did anyone actually place an order on BestBuy? I called them and as expected, they don't have it available in store for pick up but for $299 + tax and free shipping, it's still better than the egg I guess. Just wondering how long does it take to get the card since I notice they won't ship until next week.

p45 crossfire is amazing?!?

Yeah, almost 20k 3dmark 06 on 1920x1200 is not bad at all, considering i have one 2gb dimm running at 570mhz at 7-7-7-20 timings, also considering i paid $300 for both my cards out the door, and got gtx 280 like, if not better performance, im a happy camper.....also with all these mods coming out taking these cards to 800-900mhz, these are one hell of price/performance cards

How does your P5Q3 compare to these results?
I really want a P5Q Deluxe but I want to know if it will perform the same as that Gigabyte P45 in that review.

would it be amazing on this board?

I have the P5Q3 DLX, they used the gigabyte P45, maybe something is wrong with their bios??? i havnt seen these cards taking a hit yet in crossfire yet, but well see.......ill do more testing tommorow, many people want to know how P45 does crossfire, ill have some answers tommorow and more better in depth review, soon as new memory arives, microns are a big NO NO for now on the P5Q3

Are you doing cross-comparisons with X38/X48?

[GAR]

Only from websites, as i dont have an x48/x38, comparing results from various sites, my results are about the same.

Just compare against the results here first.

http://www.tweaktown.com/articles/14...nce/index.html

That will give us a quick indication if your board performs the same as their P45 one.

Yeah its the Inq but supposedly 60k+ 4870s will be in the channel by the end of June so we should see these shortages alleviated soon...

PhysX on ATI marchitecture

Source INQ

A MAD POSTER on the NGOHQ forums who goes by the name of Regeneration, claims to have hacked Nvidia’s Physx driver to bits and got it running on ATI hardware. Will the madness never end?

The post shows a screen grab of CPU-Z, the Ageia driver settings and 3D Mark Vantage with a score of 22606 CPU marks… something only attainable through Nvidia’s use of the PhysX driver within Vantage. Regeneration promises a vid of the card performing at the enhanced performance, soon.

If this did happen, Nvidia would be mightily miffed as the money it threw into acquiring Ageia would be for naught and so would its whole PhysX and CUDA marketing strategy.

Legal eagles are likely to swoop down on whoever is attempting such a deed without ponying-up a license, and legally bash him/her into submission. ATI is highly unlikely to buy into a PhysX deal, even if it is proven possible, as the company already has its own Havok-based (yes, Intel) strategy in high gear.

The question, come to think of it, is: are we actually losing anything in not having PhysX on ATI cards, considering the number of titles that support it?

That whole story is fake. You can't run PhysX on ATI because you can't run CUDA on ATI. Sorry to disappoint you guys.

[zerazax]

We'll see soon enough. But supposedly PhysX is meant to be open, only that ATI had to adopt CUDA before Nvidia allowed them to adopt it via their drivers. If all the PhysX API takes is a driver hack without CUDA, then it would certainly work on other cards

[Hornet331]

lol physx is an open api, i dont see much hacking in there...

[zerazax]

Hack was probably the improper word for "adapt"

You can't recode where the physics workload runs. You can only integrate it into your application to do physics work. Two totally different things.

You'd know how .dlls, libraries, and APIs work if you were actually a programmer.

GAR,

I will be buying a new motherboard in 14 hours time... please if you made any comparisons between your P45 and the tweaktown review please post the results so I will kow what to buy...P45 or x48..got 2 x 4850 waiting....

Interesting.

[ANP !!!]

Anyone having issues running 4850 CF on P35 ??
I am thinking of running a pair on my DFI P35.

[RaZz!]

the 4850 is a hell of a sexy card!

and it's as low as around 140 € here in germany. i'm definately on the verge of buying one - but on the other hand i can't estimate in which direction nvidia is heading with it's physx and cuda.
