4650 Beats 4670 ?

Why is it that most users with a 4650 can easily reach 7000Points in 3dmark 06.



Biogeek, me and others get just around 6900 Points? ( We all got a 4670 though!)

Also, you can overclock the 4650, meaning you could reach up to 8000. The 4670 is not overclockable.

So why is our card called 46 70 but not 46 crippled or something like that :O ?
- Isnt the higher number supposed to indicate more power, and not less?

Cheers

 

If you look at benchmarks by sites the 4650 achieves like 20-50% better fps in games, like crysis 23 for the 70 on high and 30 for the 50 on high- Is kinda weird espicially if the 50 is overclockable? The 70 just has 75 more mhz core speed so idk I guess Ati F'ed something up

 

Thats a very big let down.

Dont get me wrong, I like this Notebook a lot. But if I would have known this beforehand I might would have chosen a different one.

46F°ck.



*edit*

The reason why it bothers me is that this 46 70 was a reason to go for the notebook.
Otherwise I would have gotten a Sony FW which would have been up to 150€ Cheaper and would have had a bigger Harddrive and a faster CPU!! (500GB instead of 250, and a T9600 instead of a P8600)

I actually thought the Dell would be 30% faster. Seems like I was very wrong. 1-3% would be more accurate. In fact, if you overclock the Sony FW its actually faster than the Dell.

 

A lot of HD 4670 are underclocked, but at least I think they all should be GDDR3. Some HD 4650 are DDR2, which perform much worse. Why can't you overclock your HD 4670? Clocks for the HD 4670 should be 675/800, while the HD 4650 should be 550/800, so at those speeds, there is no reason a HD 4670 should lose to a HD 4650.

 

But it does.

At least all 4670 in the Studio XPS seem to lose against any 4650.
We can not overclock our card.

Dell seems to have locked the Bios.
I feel kind of screwed over by Dell :/

Should have went for Sony!

 

I doubt its faster, I'll bet its cos the 4650 cards are running at a lower resolutions.

 

More proof than 3dmark06 scores please.

 

I have never seen stock HD4650, either notebook or desktop, reach over 7k in 3dmark06 unless with good OC and a very good CPU.

the 7k must be with OC already, not stocks. The usual score for the HD4650 is around 5900-6000 I believe.

 

Can you overclock through software and not BIOS?

 

Mew, is that you?

Anyways, This MSI GX623, STOCK get 7200 3Dmark

Erh yeah, did I do something wrong?

 

You should be able to OC with Rivatuner or something...It may be a driver issue as well. Maybe some upcoming drivers will better utilize 4670 abilities. The only way you can really tell is by comparing like computers with the same OS, cpu, drivers, memory and test software. The folks with the higher 3dmark06 scores with the 4650 may have a much faster cpu than yours. A simple increase in cpu FSB got me almost 800 points higher in 3dmark06.

You know GPU overclocking isn't done through the BIOS... that's CPU. You can overclock your GPU via Windows software such as nTune.

^^ 4650 Look at their benchmarks, Doom and Crysis

Then the 4670 is lower in doom and crysis
http://www.notebookcheck.net/AMD-ATI-Mobility-Radeon-HD-4670.13881.0.html

Both use a quad core cpu same speed

 

Er no.
The 4650 in the Doom benchmarks is paired with a fast dual-core (the T9800 at 2.93 GHz), while the 4670 is teamed with a slower quad-core (Q9000 at 2.0 GHz). Naturally, in older single-threaded games such as Doom 3, the faster clock speed is more important than two more cores.

And Crysis doesn't even have an apples-to-apples comparison on the low 1024x768 setting! The high one does have the two cards paired with identical P8600s, and the 4670 wins by 2 fps.

EDIT: And in the 3DMark06 drag race, the MSI EX625 outraces the identically-CPU-configured Compal KHLB2 by almost 500 points on the same resolution. 'Nuff said.

EDIT 2: Getting back to the OP's point, Notebookcheck lists only ONE stock-clocked 7K+ on 3DMark06, and it's at 1280x768 paired with a P8600 (the above-mentioned Compal). The Dell Studio XPS 16 gets 6704 at full resolution - none of the other results on Notebookcheck under the HD 4650 have a comparable CPU and 1280x1024 resolution.

 

I'm not sure why it's being discussed, when the 4670 is obviously the superior silicon.

To make any kind of claim of the 4650 outpacing the 4670, is ridiculous.

 

i looked a bit more into things the guy 2 above me was right, I didint realize they used 3 diff cpus for the 50 and only posted the max- The 4670 solely performes basically what it should, 125 mhz core speed faster

 

I am mew in my Avy to

Anyways, told ya The 4670 IS better i can also throw in some more proof if you need it

 

Ridiculous, nonsense, aberration...for lots of reasons.

 

I know guys, but I was told that the BIOS of the GPU is locked.
And if I try any tool to overclock the card. It will simply crash.

Cheers
....

 

did you actually try to overclock the card?, sometimes that's the only way to find out weather you can or cant overclock.

 

can you post a gpuz screenshot of your 4670 please.

 

Sure thing, here you go! (see attachement)

Also, when I try to save the Bios in GPU Z it says Saving the Bios is not supported on this device..

 

your card has ati reference clock speeds, should perform better than a normal hd4650. but if you really want to compare it to an overclocked hd4650, know that they have a ref engine clock of 550, so it takes some luck to get it to hd4670 level.
sorry about the locked bios, my dell machine is even worse, gpuz cant even read the bios version, but i can still oc with nvidia system tools or rivatuner.

 

Its alright, you have been very helpfull. + Rep

 

I understand, well...it sucks. Maybe a solution will appear later. Doesn't change the fact you have a great mid-range gpu ;-)

 

Who told you that? You can still OC it using nTune or any other program.

 

I think I know why the gpu may be locked. If you feel the bottom of your XPS, it gets very hot. Probably uncomfortable on your lap. It means the cooling is just enough for stock speeds, let alone overclocking. (I checked out the xps myself, and went with AW). In future you might be able to OC with a bios flash or something. As is you should be able to play most games at really good res and fps. The xps is very nice. I wish you the best of luck. Did you get the RGB screen by chance? If so what do you think?

Best wishes,

StevenX

 

Have you tried this toll to overclock with, It works well on some cards that wont overclock...

http://www.techpowerup.com/downloads/1383/mirrors.php

 

Thank you all for your kind answers. As always I appreciate any input you can give to me.

I have tried this tool already, and it will just freeze on me.
Oh well.. I will just remember the "good times" with my 8600m GT which I used to overclock up to 30%

 

Though it is riskier, did you try flashing a dif/modded BIOS?

 

I did some google searching on that.
But I can not even dump my Bios. So its hopeless.
