Both cards worked well through the entire life of the gaming machine until the whole thing was replaced. And I didnt have to spend the extra cash on the high end part. Saving myself about 400 bucks between both cards.

I've done the same for a good few years.
GF4 Ti4400
Radeon 9800
Geforce 7800GT
Radeon HD4850.
Seems to work out reasonably well, better price/performance ratio than the high end that's for sure.

Yes, but your problem isn't related to performance so memory bandwidth won't be a factor. We know this because your 4870 is generating a high framerate.

The problem you're describing sounds like hitching caused by a lack of VRAM; it doesn't generally show up in benchmarks or framerate tests but it is detectable in actual gameplay.

Testing the 2900 XT could work but the problem is it?ll generate a far lower framerate than the 4870 at the same settings so it won?t be a proper comparison.

Rivatuner vram monitor only works with windows xp. Doesn't work with Vista.

Far as I know the only games that use more than 512mb of vram @ 1920x1200 is Crysis very high, WIC very high and maybe oblivion with all the mods. I'm sure there's maybe couple more games that might be pushing it with 512mb of vram at 1920 +AA.

I agree. I can run COD4, Warhammer Online, and others with AA and AF on without one problem period with my 512MB 4870. With gaming at 1920x1200 and in my opinion I really do not even need the AA on at that resolution; just no need to spend the extra $ for the 1GB cards at all. The 512 MB will handle all the games just fine until the next refresh of cards when these cards again will be "too slow" compared to the new cards.

*in bold*

yes, that IS what i think i am describing

i am thinking of now testing the 2900xt 512MB/512 bit against 2900p 512MB/256-bit - of course with lesser setting - just enough to strain the graphics system while comparing "smoothness" at what is considered playable resolutions

i got my GTX280 up and running. i am looking forward to seeing how it does in these same games that are not smooth with 4870

The X2 can be run with a core disabled - and it is generally [across-the-board] slightly slower than a 4870

Thanks for the confirmation.

There might be a benefit in Crysis for additional ram, but the GPU is too slow to benefit from it. A quick search around the net shows none of these single cards are good enough for 1920x1200 4AA for the games where there *could be* a benefit from having > 512mb of ram.

You can see the cards are already so strained to begin with, going beyond 1920x1200 where 512mb will be a bottleneck will bring all of them to their knees anyway.

We are not going beyond 19x12 in my tests. And the hitching is seen - obvious and irritating - when the minimum FPS is *above 30*
--we need to look at "smoothness" of gameplay

screw looking at "min-average-max" FPS figures :p

they say nothing about "smoothness" of game play

:Q



almost nothing

I am not doubting that you are having problems. You can see from the benchmarks above that these latest games aren't playable on either GTX260 or 4870 at 1920x1200 no matter how you look at it. That's why going beyond 1920x1200 to expose further memory limitation is already pointless since they can't even manage 19x12 to begin with.

But the fact that 2900XT seems smoother than your 4870 with same 512mb is odd.

If that's the case, that doesn't help with the argument that 1GB > 512mb on mid-high ends cards?

You misunderstand me - when i load each card to the point where the FPS drop near 30:

1) my 4870[x1] when *strained* at 19x12 will exhibit irritating hitching
- even though the FPS are above 30

2) my 2900xt when *strained* at 16x12 - will not exhibit this
- even though the FPS are also barely above 30

3) my 4870 when *strained* at 19x12 [much more than 4870; by adding 8xMSAA] will not exhibit hitching [like 4870x1 does]
- even though the FPS are also *barely* above 30

they are not both running Crysis [for example] at 19x12 with identical same settings

my POINT is that - although the minimum FPS indicate 4870 should be smooth - it is not

The 640 MB G80 benefits more if overclocked - the GPU ist just too slow as are the Shaders. Clocking mine to 650/1000 makes quite a difference and also utilizes the 320-Bit Bus more.

If you give it more clocks, also the benefit of the additional memory vs. the 320 MB version becomes greater, because you can actually make use of it in some games.

I didn't notice anything like you're describing with either my 512MB 8800GT or my 512MB 4850 while gaming at 1920x1200. Sometimes I noticed low framerates, but nothing that couldn't be attributed to lack of GPU power.

Are you sure it couldn't be hard drive activity or some other process causing the hitching? My system specs are nothing extraordinary. Stock Q6600, stock 4850/8800GT, 7200 RPM SATA-II hard drive and 4GB memory on Vista 64 Ultimate.

Of course there is. Some parts do out last than other parts.

There is only future "resistence" parts. In the end they all become less than adequate eventually. Some take longer than others.

yes

there is no unusual HD activity or swapping to disk
--i know that one :p

no, it is a "choppiness" or a lack of fluidity which i notice more with my 4870 than i do with my 4870x2 or GTX280

it is only really noticeable at 19x12 when maximum details and filtering are way up; and the FPS stay constant above 40!!

Define "future..."


.. later, perhaps .. when it will have arrived

Well like I have posted I get smooth as butter gameplay on my VisionTek 4870 512MB card. It seems like some experience no issues and some do; so maybe it's hit and miss?

Well, what would you call gameplay on an X2 then?
-smoother than butter?
:confused:

You have to realize that i am not talking "choppy" .. but we are used to a certain "fluidity" as one frame flows into the other. It is just that 4870 lacks a bit compared to the GTX280, for example.

You need something to compare to. And what i notice is not across-the-board; it is in heavy 19x12 situations - in certain games - that really strain the graphics card and YET it still manages to keep a minimum frame rate over 40 FPS.

i guess the only way to describe it is to upload a FRAPS video, but just creating it has its own sets of problems [besides the fact the video file is SO huge]

if anyone knows a better way to demonstrate or quantify relative smoothness - besides FPS charts, LMK.

it is going good - if a little slow
.. the 1GB vRAM does not look so useful for 4850 which is a bit limited for 19x12, anyway.

i re-did so many of my benches on my other partition to confirm what i thought i was seeing with stuttering. Part 1 will be done this afternoon - e4300@3.33Ghz and much more exhaustive testing with stock e8600 [3.33Ghz] and 5 GPUs - GTX280 and 8800GTX compared to HD4870, 4870x2 and 2900xt. All i have left is a few tests left to run for my 2900xt - 3 games, a couple of hours at most.

All i have is the raw figures, so far. And a lot of 'impressions', suggestions and conclusions. Next, i am testing this evening - limitedly with HD4870/512 + HD4870x2 for crossfire X-3 on a P35 MB - and then, tomorrow night - i am rebuilding my platform with x48 MB and O/C'ing my CPU; i already got my e8600 to 4.5Ghz and was able to run programs in Vista, but i did not tweak it or test it for stability yet.

Nah it's okay. No rush :) Just link us your article once you get everything sorted out.

With Crysis Warhead on Sept 16, Brothers in Arms: Hell's Highway on Sept 23, Far Cry 2 on Oct 21, Call of Duty: World at War on Nov 11 we should get an even better indication of 512mb vs. 1GB argument.
