Nvidia GTX465 preview with benchmarks from xbitlabs

Thats a bit rubbish really and you can't compare the ME2 results nVidia to ATI (where it does look a little better) as the forced AA methods are different between the 2 (ah the joys of the unreal engine and deferred lighting :D)
 
Are there any 275gtx's in stock anymore, havent' looked in, well, ages, if you can pick up the last few 275gtx's for sub £170, and get almost the same performance in any situation you'd want when paying over £200 for a card, just ouch.

Its a really horrible card, and the mobile part can't be all that good either, supposedly about a 465gtx in specs, but, at 425Mhz, which I assume allows a massive voltage reduction, even at 425Mhz the mobile version of this will be insanely high power, for, half a 275gtx in performance? Not a good day for Nvidia in terms of products being "released" and all the news being well, not at all good.

I think its also safe to say, if a 256bit, 1gb, 352shader, 600Mhz part can't really beat a 275gtx, a 256shader version of the card, with similar/same other specs, well, is going to be significantly slower than a 275gtx, so no chances their midrange will significantly beat a 5770, yet I'm still expecting that midrange part to come in around 5830 price(for a performance varient, I reckon a 512MB, slower clocked mid end part might not be much above a 5770 in pricing, but will probably be slower).
 
Couple of places still have 10+ units of various lines, tho they are getting harder and harder to find.

Its a bit ridiculous that a 352SP 400 series card struggles to beat a 240SP 200 series tho :S the only thing it might have on its side is possibly nice OCing headroom - but even then its no GTX260. Its like if the GTX260 had only been as fast as the 9800GT/8800GT lol.
 
The problem is, generally "salvage" parts, a 260gtx, or a 5850, 4850, they tend to cut down one, or maybe to specs properly and the rest much the same.

The 5850 only has some shaders cut, and this gen being far from shader power limited, but being rop limited/core clock limited the 5850 is a beast and are in general can overclock incredibly well.

Though have to say I'm having a mare with xfire, though most of that is down to a 5850 from launch, and a Asus Cu from last week, different bios's, different default clocks, different default voltages and no single program can set voltage on both cards at the same time, its incredibly difficult to overclock them at the moment, i'll set voltages through Asus's own app(which is truly and utterly awful) which then changes the idling speeds back to 157/300, which with two screens doesn't work well at all(flickering) if I use another app to fix the idle speed, the overclock changes.



ANyway back to the Fermi's, I agree with you, its ridiculous that a 352sp card can't beat a 240sp card, I can't recall the fermi specs off the top of my head, was it TMU's they cut down compared to the gt200b's? Thinking they overshot how many they needed last gen, this gen they got it right for the 480gtx, but as you cut them down its becoming a limitation? Hmm, it shouldn't as I would expect the only thing using tmu/rops is things being done within that single cluster, so it should maintain the same balance per cluster.

Its really just down to the 480gtx not being fast enough over last gen compared to what it should be. If the 480gtx had the 80% bump it should have had over the 285gtx, the 465 would have a healthy lead on any last gen card.

I really can't explain it though, even if its not as fast as it should have been, I still struggle to see how 352sp's can't beat 240sp's, the shaders themselves are unlikely to be less efficient, but the whole cluster, shader/rop/tmu setup being together might of ended up far less efficient, its not a massive core speed disadvantage, and a 240sp with a minor clock advantage matches a card with 50% more sp's.

The funny thing is the same situation seems to be have been repeated with the HD5830 when compared to the HD4890.

OTH,at least the price of the HD5830 is starting to drop towards £150.

I just picked up a GTX-275 for £103. Easily worth it considering the price i got it for.
 
Latest update to that XS thread is promising, dude has the 465 @ 891 core on stock cooler. If these come in ~£175 or less at retail they might be a decent option, i doubt that will happen if XBit's RRP is correct + the obligatory price gouging that goes on though.

Only a few days until Computex so i guess we'll know soon enough. Still hoping GF104 will launch at the same time but i'm not sure that'll be the case any more.

Someone is selling the ASUS model already for £279.99 on a well known auction site.

Will anyone pay that??? Seems a dodgy deal all round. Let's wait and see the true prices and performance vs 5830.
 
If the mobile GTX480 which is essentially this is so damn slow with low clock-speeds isn't there a chance the GTX280m could beat it?

So G92 LIVES?!?

1. A lot more of the core has been moved into the shader domain in FERMI.

2. The 480m has a lot more shader power and 30% more memory bandwidth.

There shouldn't be but you never really know. If the 465gtx is really on par with a 275gtx, dropping the speeds by, what 33% for the mobile part, with much lower speed memory, its going to be significantly slower than the 465gtx/275gtx, but then a 280M is only 128shaders, realistically the 465gtx would need to be clocked at around 300-350Mhz for the 280M to beat it, though it is a relatively full speed part. Shaders are rather speed x amount = performance, lower clock speed won't hurt them, but the rops being at a very limited speed could really hurt it, I can see there being certain games where the full speed rops on the 280M actually beat the 480M.

They are really just asking for trouble calling it a 480m, at least have some balls and call it a 465M and bring down expectations, its going to be horrible.

The 5870 mobile, I have to say I've not checked performance but

http://www.amd.com/US/PRODUCTS/NOTEBOOK/GRAPHICS/ATI-MOBILITY-HD-5800/Pages/hd-5870-specs.aspx

Its basically a 5770 isn't it, maybe 5750, depending on clock speeds, so in most situations you'd expect it to beat a 4870 and be beaten by a 4890, which only puts it a bit under a 275gtx and should be way ahead of a 480M shouldn't it?

50Watts aswell for what probably ends up being faster than the 100W 460M. lol, someone should make a great hulking laptop with quadfire 5870 mobiles to go up against sli 480m's.

Thing is, Nvidia has this slight habbit of over estimating specs before the release, so lets see if specs drop even further by the time they are actually in laptops.

I really can't see anyone wanting to make this laptop, its more a case I reckon of Nvidia persauding someone to come up with a couple designs, make a few available and Nvidia will do a deal on some other mobile cards for them. Its more important that it appears available and working, than it actually needs to sell in large numbers. Again its "we can make it" rather than AMD and Intel going "look, they can't even make a laptop with it in" .

Though, a 280m I just read is a 75W part, so 100W isn't that much more for probably decent amount better performance in at least some games, but is the 100W Nvidia's new TDP.

Meh, either way, surely anyone with half a brain would take a likely faster, and only 50W 5870 laptop over something with double the power and likely slower performance.

Then again, its absolute madness to use a cut down full size GF100 part for mobile parts, rather than midrange parts.
 
480m looks like being roughly as fast as the reference GTX260, tho the memory clocks and hacked up ROPs/TMUs might cripple it further, hard to say at this point. I'd hazard give or take it would mostly put up similiar performance to the desktop 5770, with a slight edge in DX11 stuff and a few percent slower in older DX8, DX9, etc. games
