Mobile Platform Wars: AMD vs. Intel

HP 6515b Internals
During the course of testing, we became more than just a little familiar with how to open up the 6515b and swap processors. We also performed a memory upgrade to take the system from 2x512MB of RAM up to 2x1GB. Either upgrade starts with the same step: remove the center cover on the bottom of the laptop.
Behind this panel, you can find one of the SO-DIMMs as well as the mini-PCI WiFi adapter. One of three screws that need to be loosened in order to remove the keyboard is also behind this panel.
Besides the three screws on the bottom that hold the keyboard in place, there are four plastic tabs across the top of the keyboard that need to be disengaged. After that's done, the keyboard can be lifted out of the way revealing the second memory slot as well as the CPU and its heatpipe cooler. The plastic panel above the keyboard can be popped out, which gives access to one of the two screws that holds the heatsink fan in place. After removing the fan, you can then remove the heatsink and swap out processors.
It might sound a little complex, but in reality this is one of the easier CPU swaps we've done on a laptop. Once you're familiar with the process, it's possible to swap out the CPU in under 10 minutes, and given the need to run certain benchmarks on a clean install of Windows Vista, we had to swap CPUs back-and-forth over a dozen times before we were finished with testing. We're also happy to report that during all this time, we didn't experience any system crashes or other instability that would give us cause for concern.

Since we talk about bargains i guess a comparison between the previous generation mid-range (Geforce 7600, ATI X1600) and the entry level graphic chips (Geforce 8400, AMD/ATI HD2300) would have been nice.I find myself choosing between 2 HP's almost equal specs (almost no differences between AMDX2 TL60 and Intel T5500) but one with ATI X1600 and the other with the 8400GS. I'm almost sure i will takle the X1600 because of build quality and screen, but i would have liked some numbers regarding 3D performance.

Nice summary Jarred.I was a little surprised to not see anything about video quality. I, for one, don't do any gaming on my notebook but I do watch DVD movies while traveling. It seems the only way AT measures the success of "graphics" is how well they play games. Any thoughts on comparing systems on other visual aspects?

I guess the real problem is that I think most laptop LCDs suck, which means that even if the video card does an excellent job at decoding DVDs or whatever, the display quality makes this a moot point. I didn't think the 6515b was any better or worse than the dv6500t (or any other notebook, really) when it comes to DVD playback. Of course, you can always just get a different DVD decoder application that can make a big difference. DVD decoding is now at the point where the CPU can do all the work and still only put a moderate load on a CPU, even with higher complexity decoding algorithms that improve image quality.Maybe I didn't pay enough attention, though, so I'll see if I can notice any difference with additional testing.

Thank you very much for this article.I've been looking for a new laptop for the several months, and have almost settled on one of the 6515b, 6510b (if I can find one in Australia) or (most likely) the 6710b.
I've been searching for months trying to find comparisons of the laptops with anything near the configuration I'm looking at (T7100/GMA X3100, or Turion X2/X1250). The 6515b is pretty much out of contention though since to get an X2 you have to go above the price of the T7100 in the 6710b (the cheap 6515b comes with an MK-38).
It's not going to be a desktop replacement, but it needs to be grunty enough for serious work, and needs good enough graphics to play things up to the level of Guild Wars at native resolution (1280x800). I had a work laptop recently with a T5500 and GMA 950, and GW was playable (but not great - 20-30 FPS most of the time), so I have reasonable expectations of the 6710b. Interestingly, my home server (E2140 with G33/GMA 3000 graphics) has worse GW performance than the GMA 950 - my understanding was that GMA 3000 is basically an upgraded GMA 950, but there appear to be significant differences (GW detects the GMA 3000 as DX8 but GMA 950 as DX9, even when both have the 14.31.1 driver).
I'll be *very* interested in the X3100 results you get under XP (with the 14.31.1 drivers).
BTW, one of the reasons I've settled on the HP laptops is their look and feel. They are simple-looking, no-nonsense designs, that aren't going to show marks, the keyboards feel very nice, the screens are good and the sound is quite good for a laptop.

I'll spoil the results a bit and say that under XP, GMA X3100 appears to best X1250 across the board. Shockingly (pardon the pun), it even runs Bioshock - okay, so it's at about 20FPS at 800x600 (minimum detail), but at least that proves it's mostly drivers under Vista keeping it from running the latest titles. I should have the final article done next week, showing X3100 XP results. Still, for $80 more you can get HD 2300 which remains about 2-3 times as fast, or 8400 GS which is also around 2-3 times as fast.yyrkoon - Sunday, October 7, 2007 - link
I honestly think your time would have been better spent covering some other aspect in the industry. Everyone knows that AMD is in a "rutt' at the moment, and this article really only tells us what we could have guesses on our own. Reasons for an article of this type in my own opinion would be; ground breaking news, or at the very elast a much shorter article just covering the import stuff such as AMDs mobile graphics superiority.There are lots of people out there, with myself included that would like to see you guys do an article on something like SAS IN DEPTH, or SATA Port Multipliers, with benchmarks, implementation, etc.
Also, just going from past experience of reading your articles, I cannot help but wonder why you guys do not have any how-to's such as 'how-to overclock an Intel core 2 CPU . . ', or 'how-to build a cheap storage solution with SAS/HPM technology . . ' , etc. I honestly think filling content with things such as the above mentioned how-to's, would be far more benificial to your readers, than the obvious re-iteration of things we already know.

Oh? So that's the only thing that's important? It's dubious that you'd pick one of the few bright spots in the article for AMD and tout it as "the important stuff".
yyrkoon - Sunday, October 7, 2007 - link
How would it be dubious that I do not care to hear about the same thing I have been hearing about for the last several months ?zsdersw - Sunday, October 7, 2007 - link
What you do and do not care about is not what's dubious. What's dubious is that the only thing you supposedly regard as "the important stuff" just happens to be the one area of mobile platforms where AMD generally fares better than Intel (mobile graphics chipsets).yyrkoon - Monday, October 8, 2007 - link
Look guy, if you're going to call me an AMD Nazi, fanboi, or whatever, why dont you just come out and say so, instead of making stupid comments that MAY imply *something*. You would be wrong by the way.
