http://www.tomshardware.com/reviews/deepcool-dracula-radeon-hd-7970-cooling,3246.html Interesting article on Tom's Hardware in which they test a custom 5-slot cooler for a Radeon HD 7970 GHz Edition. I found it neat that the fans aren't actually touching the heatsink.

It would be interesting to compare that with the performance of the Arctic Cooling Accelero Xtreme 7970.

Just found some leaked info about Team Green's 660Ti. If it's to be believed, it'll be virtually identical to the 670, except for a 192-bit bus width. http://www.sweclockers.com/nyhet/15694-geforce-gtx-660-ti-specifikationer-och-lanseringsdatum

Jesus, they are stingy with buses these days. I remember when all the top end cards had at least a 512-bit bus, granted much slower RAM, but we already know Kepler is shackled to the bus from overclocking it. Cripes. If it does launch in that configuration it'll be a price:performance monster and confirm my suspicion that nVidia is making these things cheeeap compared to ATI, who really can't afford another cut to meet a less bandwidth version of the 670.

Heck, I thought that the 256 bit bus could saturate PCIE2 x16 in SLI mode. Yes, bus width by VRAM speed contributes to total GB/sec bandwidth. Memory buses on current gen cards are made of 64-bit chips working together. Fermi GF110 called for a combined 384-bit bus and about 4GHz GDDR3. ATI ran faster RAM on a 256-bit bus. This gen, nVidia did faster RAM, narrower bus, while AT did 5.5GHz GDDR5 on a 384-bit bus. Old cards needed big memory buses because the memory was slow (the introduction of on-card DDR3 was huge in its day). New cards can get by with less, relying on SLI/Crossfire for parallel access times for super demanding activity. It's also more demanding on the integrated memory controller found inthe die to run at faster rates, so I'm only kvetching, really, but nVidia actually is rather memory bandwidth limited and that shows up when you begin to really overclock it, have to spend TDP on VRAM speed to get it up to where you can see the benefits of a hefty core overclock. ATI too but iirc less so.

Josh Lyman posted:The market of people who buy cards based on memory bus bandwidth is super small. Not so sure, look at the various GTX 460 SKUs and how deterministic the bus was for performance once they hacked a big chop out. People cottoned on to the performance difference quickly. An unmodified GTX 670 with a 192-bit instead of a 256-bit memory bus is about the most effective and simple way to artificially limit the card's performance by a substantial margin while still making it competitive in general with any price:performance options currently on the table. For lower resolutions (1080p) may well be a new card of choice; for very high resolutions, two in SLI could lose to two 7870s going on napkin math alone.

Isn't chopping the memory bus a good cost savings in manufacturing as well, compared to some other things?

I'd imagine so; fewer RAM chips to make up the set. A 192-bit bus could be done in six chips instead of the eight for the 670/680. Plus with the possible length savings from rearranging them: (from LegitReviews) ... it might be possible to shrink the card somewhat, though that's a trade-off with engineering resources an validation. What it also is is a way to harvest chips effectively. GPU RAM controllers tend to be distributed physically, and on GK104, they're distributed around the edges of the SMX groups.  (from AnandTech's GeForce 680 review) The actual connections are distributed in an on-chip interconnect network, so it's not like those controllers solely handle the SMX pair they're next to. But this allows re-using chips which have a bum memory controller, either flawed in manufacturing or unable to run at the speeds needed. I think the latter part, harvesting subpar chips, is more the point. Say Nvidia made $250 per GeForce 680 per GK104, or whatever. Without harvesting, a single flaw in an SMX means no money for that chip; instead sell it for a GeForce 670 for $200, and you've turned garbage into $200. Got two flaws, or the one flaw is on the memory controller? Sell it for $150 as a 660 Ti, and you've turned garbage into $150.

What's a good brand for nVidia cards that's not EVGA these days? I'd been going with EVGA, but I'm on my third 460 from them and it's still not stable at stock speeds, so I'm not feeling so impressed with them anymore (and the warranty isn't seeming like such a plus).

Asus, MSI, Zotac. Also, what the hell use do you expect the warranty to be if you have a broken card and you aren't using the warranty to get it replaced with a functional one?

I tried twice, but apparently they weren't interested in sending me functional replacements. At that point I decided to deal with the one that at least worked underclocked rather than risk going through it again just to get another card that didn't work at all.

That's some bad luck since I have a EVGA 460 that's been stable for months.

TweakTown got their hands on a 660 Tiquote:It's hard to fault NVIDIA's upcoming GEFORCE GTX 660 Ti and for good reason. You're talking about a video card that is rumored to hit at the mid-$200 range yet performs like a video card priced $100 more. In this case we're talking about the HD 7950 specifically. You could argue that it can be compared against the more expensive HD 7970 at times, too. http://www.tweaktown.com/reviews/4869/nvidia_geforce_gtx_660_ti_2gb_reference_video_card_review/index.html

Geno posted:TweakTown got their hands on a 660 Ti gently caress me, it is a 670 with a 192-bit bus. This is going to really hurt ATI. Holy gently caress nVidia is on fire this generation. Edit: Two things - one, man oh man is this card bandwidth limited. I mean, by design, but still. I would guess you could get some pretty impressive performance improvements just by overclocking the GDDR5. Number two, nVidia is making these things cheap. This is probably the base level for them to turn a profit on the card, which is just brutal considering how much I'm guessing ATI is cutting it close to the bone on their performance lineup after price drop #2.

So, I'm looking at getting the fabled 690 GTX. Although, I'm using a LGA 1366 socket motherboard due to the fact that I'm running an i7 990x. After doing some research it seems that the 690 will work on PCI-E 2.0. Now, my main question. Will the 690 GTX work with a GA-X58A-UD7 motherboard. If it won't, would someone recommend me a LGA 1366 motherboard that will allow it to run? Thanks. reboot fucked around with this message at 03:22 on Aug 1, 2012 |

Unless you're in some crazy one-in-a-million situation, you're better off buying a 670 and putting the other $600 or so in an envelope. The second the 670 starts being annoyingly slow, open the envelope and buy whatever's top-of-the-reasonable-line.

The second the 670 starts being annoyingly slow, open the envelope and buy whatever's top-of-the-reasonable-line. Thanks for the answer, appreciate it. The reason I'm doing it is that I've decided to switch from liquid cooling and have dual liquid cooled 580 GTX's. I'm going to be selling those and getting what I can back and putting it towards the 690. It would only wind up being a maybe $300 upgrade, which isn't bad at all. My motherboard also died, which is a real pain in the rear end, so I was just thinking it was time to get away from liquid (which has given me so many problems in the past) and just switch to air while I still have a reason to make any changes.

It's difficult to buy a GPU at a time when you couldn't get a more powerful card for a similar price 4-5 months later. If you only upgraded for the hell of it then this would've been a nicer score but the 7850 owns.

I'm trying to figure out how much faster a 7750/1GB/GDDR5 is over a 6670/1GB/GDDR3. http://www.newegg.com/Product/Product.aspx?Item=N82E16814131461 http://www.newegg.com/Product/Product.aspx?Item=N82E16814150576 I know the 7750 is faster but by how much? I'm picking between these due to space constraints I need a single slot card that doesn't need external power.

I'll answer your question with another question: is it possible for you to swap cases/motherboards to use dual-slot cards and a larger PSU? I'm just curious as to what's keeping you constrained to that selection range (i.e. you need a super quiet mini-ITX box for the living room or something).
