Which is better for gaming? 6770m or 5770 PCIe?

Yes it does matter. If it takes around a year to release a mobile chip with the same performance as a desktop chip, then mobile users have to wait that much longer before they can even try to get the same gaming experience as desktop users. And btw, the 8800/9800 GT was originally produced with a 65 NM process.

The 9800GT was originally produced on a 55nm process. 65nm "9800GTs" are rebranded 8800GTs, which were on a 65nm process. And your time argument, I don't know how it's relevant or makes sense to the discussion. I'm just stating the fact that mobile chips deliver the same performance as their desktop performance equivalents, but at much lower power consumption. That, and they have higher heat resistance.

They obviously cost a lot more, though.

No, it wasn't. The 9800 GT was transferred over to a 55 nm process, but initially it was 65 NM, a carbon copy of the 8800 GT. I own a 65 nm 9800 GT. Also according to GPUreview.com, the 105 W max load number for the 9800 GT goes along with the 65 nm process: http://www.gpureview.com/show_cards.php?card1=544&card2=575 (the 8800 GT is shown to have the same process and power draw). So it did take a process shrink and extra time to get that low a power draw for the mobile chip.

The 65nm 9800GTs are rebranded G92 8800GTs. The 9800GT (not the 8800GT rebrands) is 55nm. The 105W 9800GTs are real 9800GTs, not the rebrands.

If the 105 W 9800 GTs are the 55 nm versions, then why does the 65 nm 8800 GT consume 105 W as well?

I got confused. Yes, the 105W is the rebadged card. I looked around and couldn't find numbers for the real 55nm 9800GTs. However, taking into account the 65nm, older version of my card was 75W, it's a good informed guess that the 9800GT is ~95W. Still a 30W difference, which is pretty darn big.

Ah yes I recall this caused quite a stir in the community. Releasing a new line that was slower than the old one with the same series. Anand commented on it too.

Keep in mind price can sometimes (not always) help give relative performance indicators.

Based on dollar signs you may be tempted to believe the 6770 is faster.

huh? They're comparing a mobile gpu to desktop. A 6770m isn't even close to a 5770 (or a 6770 desktop for that matter), just look at the specs listed in post #2.

Super high end laptops can and do beat mid range desktops. A mid range desktop would have a gtx 560/570 level graphics, a super high end laptop has two gtx 485m's in SLI, that is basically 2 gtx 460's or gtx 580 level.

Yeah, a better description would have been high end laptop ~ low/mid desktop. On the super high end a laptop can be pretty competitive with even a decent high end desktop, it just costs 5x as much.

The poll is pretty slanted. The 6770M would have likely been faster if they didn't cut the ROPs to 8. If the 6770M was exactly 1/2 Barts (which it is in every way, asside from ROPs), it would have likely been very close in performance to the Desktop 5770. As such, the 6770M is about 35-40% slower.

But, BTW, I own an 6770M and it currently plays pretty much anything I throw at it with full settings. Of course, part of this was strategic planning of a 1366x768 display, for less ROP work.

768P W/ 6770M = about the same speed as 1080P W/ 5770

Different chips though. One fits in a laptop, consumes less than 30 watts under load, the other is around 100 watts or so.

I wouldn't call those 'laptops'... Perhaps a mobile workstation? Putting those mega performance machines on your lap will result in some toasted nuts.
