Vision Tek 4850 review

[BRiT]

Wow look at the minimal perfomance hit no AA vs 4xAA in COJ. 3800 had the same behaviour? I've never played COJ

You mean 2x AA to 4x AA.

I guesstimate like 10,000PPD for 4870X2 Crossfire!

Thanks jimmyz, but when should we expect the rest of the benches ??? Again thank you very much, for the time you spend to share these results with us.

/agree and I echo the question .

Looks like a winner at its pricepoint...waiting for more!

[cl55amg]

me too the 4870 have 1gb of gddr5.

I thought the 4870 has 512MB and a 1GB version is coming short after the release?

Of course I hope they bring the 1GB version asap, but can they still keep the price that low then? How expansive is GDRR5 memory?

NOP , i think HD3800 drops Fps when AA enbale (Hd2900 same thing) , so probably AA is Fixed

I'm hearing $299 for the 512 and $329-349 for the 1GB around the various forums... sounds reasonable to me. The memory's expensive but not so expensive it will boost the price obscenely.

/me continues drooling for more benches, and can't wait to see the 4870 in a few days too!

Thanks man, this is getting better. Looking foward to more AA vs no AA test.

[adamsleath]

nice to see some trustworthy results. i'd like more than 512mb aswell.

[informal]

Very fine work jimmyz
Seems AA causes almost no hit with the new Radeons,when enabled.Great news,waiting for more tests.

Stargazer,seems your wish for real gaming results is coming to fulfillment
IF 4870 performs ~30% better than this,than GTX260 is in deep ***,especially when factory OCed versions of 4870 hit the shelves(can you say 40% faster than todays 4850 tested here ? ).Oh also,Crysis appears to run good on new 4850 .

Yep, I'm gonna try to sniff out the 1GB one personally.

[eleeter]

I scored 1580 on my system on extreme settings, GPU score 1460.

I need an upgrade.

Wouldn't 1GB of VRAM only be beneficial (compared to 512MB) at very high resolutions? I guess very high resolution textures might be a factor as well.

Anyone care to clarify?

High resolutions, high anisotropic filtering, high texture resolutions... beneficial for many things. Crysis Very High, HL2 modded with Cinematic Mod 7, Oblivion with QTP3/other mods push 700mb or more of memory at 1680x1050-1920x1200. There's other games too of course but those come to mind immediately.

Really? I figured the 256MB of VRAM on my 7800GTX was throttling me down most of the time, considering I run at 1680x1050.

I guess I should consider an HD4870 1GB then... Though it always seems that 1GB versions of cards are ridiculously more expensive than their 512MB counterparts.

Oblivion with insane textures is what i cant wait to play

[Loser777]

I want my 20k 3dm06... with CF, it looks like I might finally get it.

[Chickenfeed]

All the 1GB cards to this point have been complete and total marketing schemes. The 1GB GDDR5 on the 256bit 4870 and the 1GB GDDR3 on the 512bit GTX 280 will make for the first cards that use this extra memory as more than a gimmick.

The differences on Crysis at 1920x1200 4x AA between the 4850 and 4870 1GB should be substantial (neither will be playable though )

[fcry64]

^no..i think both will be playable:thumbsup:

[GoldenTiger]

been hard pressed for time today, and internet has been going out along with the power. here is the first round in vista 64 ultimate.

As you can see it seems to scale well with the high resolution, I still can't get Crysis to run the proper bench, it keeps starting the game in the window instead, any ideas?

Just press alt+enter when it's running and it should run in full-screen again... and any more times after that you run it. I had the same issue once with my 8800GT 512 and couldn't figure it out at the time either .

[fcry64]

^if the window res is 960x600, alt-enter-ing to fullscreen will be still the same res

settings the game.cfg res to desired will help(in my games folder) . do remember to click the command promt/dos type window when u get teh message 'press any key to ....' don't click anywhere else when u do that(out o the window)

hope that helps for certain

It's the drop from 2x to 4x, if you look. As such, the small hit isn't too surprising.

Although, COJ isn't the title to test to see if AA performance is fixed. Why? Because COJ forces Shader based AA, so it's doing AA exactly the same as the R6xx in that title.

If we really want to check on the AA/AF hit, you'll want to use a title like Oblivion or UT3. Something that doesn't force specific methods of AA(even Crysis doesn't use traditional AA methods).

[natty]

^no..i think both will be playable:thumbsup:

they wont

at least not on very high

[Benji Tshi]

Don't forget my favourite bench : 3dm03 ! It seems that this little card is quite interesting.

[kemo]

Nice thread m8 , keep up the good work .
