Mobile Platform Wars: AMD vs. Intel

Test Setup
We've previously reviewed the HP dv6500t, which will be representing Intel's Core 2 Duo for this article. Again, this is not strictly an apples-to-apples comparison between products, as there are various differences besides the choice of platform. The HP dv6500t is a consumer laptop and it comes in a 15.4" chassis. Besides the slightly larger chassis and a flashier exterior, HP allows users to customize the consumer laptops. The 6515b on the other hand is a business laptop, and there are specific preconfigured models that are available for purchase. The model HP shipped us included a TL-60 processor and 2x512MB RAM, but we strongly feel that any modern notebook should come with at least 2GB of memory so we made that upgrade. Once both laptops are similarly equipped, prices end up being roughly the same.
The HP 6510b represents a better price/platform comparison, as it comes with a similar chassis and features, and again the prices end up being nearly the same. We were unable to get a 6510b for this article, but other than the change in chassis the performance should be nearly the same as the dv6500t. Here are the details of the two test laptops.
The dv6500t comes with a 2.0GHz Core 2 Duo T7300, which provides a clock for clock comparison to the Turion X2 TL-60. The batteries included with each laptop aren't quite the same size, as the 6515b comes with a larger 55WHr compared to the 47WHr on the dv6500t. We also need to be careful when talking about battery life and power requirements as the 15.4" display on the dv6500t may require a bit more power than the 14" display on the 6515b.

Jarred, you wrote "Even better would be a midrange HD 2600 or GeForce 8600M/8700M, though those tend to only be found in laptops that cost over $1500" - this is totally not true. I've got myself a nice Dell Vostro 17" laptop last week, with Vista, Core 2 Duo, all the shebang... AND A REAL NVIDIA 8600M GT 256M VRAM inside, for <drumroll> $1049 </drumroll>So why don't you change your number from $1500 to $1000?

There's a difference between "tend to be" and "absolutely are not available for less than..." I checked out the Vostro 1700, configured a minimum cost version with the 8600M GT 256MB, and ended up at a price of $1249. That's with a Core 2 Duo T5270 (1.4GHz 2MB cache). I'd say T7100 is a better minimum choice, and probably would look for a T7300 instead personally. That would put the price pretty darn close to $1500 ($1459 with the T7300). That's also with a current rebate to bring the price down from $1881 ($1671 minimum cost), which may not always be available.I'll take out the word "only" as it's superfluous, but I stand by the statement that most laptops with 8600M -- that aren't on sale -- will be very close to $1500 total (shipped).

First up, nice article.Second thing, did you notice if one system had any defining characteristics compared to each another? I've been pretty much an intel user for the last 18 months, but previously I was an AMD-holic. While P4s were about, you could notice that the UI responsiveness and load times were kind of strange for intel P4 systems compared to AMD Athlon systems - they would often be a pause or stutter on an intel system when an AMD system would just feel a lot smoother during UI operations and associated disk access. Okay, so that could have been due single core, possibly also due to cache misses and stalled pipeline on the P4, so this might be a useless braindump.....but a quick throw away comment in response to this post as to whether the architechtural differences translate in to a different feel when you're driving a system would be cool...even if it's to tell me to get a grip :)

Generally speaking, both laptops perform fine in Windows Vista. Without running stress tests or benchmarks, only the exterior would really let people know the difference. Interesting to note is that the Intel setup gets a 3.5 Windows Experience score while the AMD gets a 3.0, with the low score on both coming in the graphics department. Apparently, the lack of SM3.0 limits the AMD setup to a maximum score of 3.0 (the same score I get with an X800 desktop system).The bigger differences are in the styling and keyboard layout. Obviously, being a business laptop the 6515b is pretty boring looking. Honestly, though, I didn't mind that part. The dv6500t does come with better speakers as well as two headphone jacks. I think the display on the 6515b might look a bit nicer, but neither LCD is all that great. If I were to choose, though?
dv6500t with T7500, 8400M GS graphics, 2GB RAM, 160GB HDD, 802.11n+Bluetooth, and a 3-year warranty runs about $1350 and represents a pretty good deal. Drop to a T5250 and you get the price down to $1300. The dv6500z with identical options (8400M GS, 2GB, 160GB, 3-year) based on an AMD platform with a TL-64 comes to about $1350. You can drop the CPU down to a TL-60 to save $100. You can also ditch the 3-year extended warranty to bring either option under $1100. The dv6500t ends up at $1092 with T5250 and the dv6500z costs $1062 with a TL-60.
$30 more and the Intel platform should be about 15% faster on CPU tasks. Not enough to really notice, true, but it's also only increasing the cost by around 3%. I'll spend the $30 for sure. Maybe some other company can do Turion X2 for less, but I doubt it. CPU cost is only a small part of the whole.

well since you would choose from the budget systems for the more expensive systemwhy don't you first give us an idea how the raw cpu performance will differ from T7500 vs T5250 and for sure a t5250 versus tl-60.
because in that budget round on price/performance you should think twice. The tl-60 will outperform the T5250 on everything exept power consumption.
JarredWalton - Sunday, October 7, 2007 - link
No it won't - not even close. Look at the results in this article. A T7300 outperforms a TL-60 by an average of 25%! Do you know what a T7250 is? It's a T7300 with half the L2 cache, which causes a loss of 5-10% performance for Intel (so we're down to 15-20% performance advantage on average). Both will run at 2.0 GHz, and clock for clock AMD is at a disadvantage. Sorry, but your guess is way off. A Pentium Dual-Core running at 2.0GHz would basically match the AMD dual-core offerings clock for clock, but those tend to be cheaper.JarredWalton - Sunday, October 7, 2007 - link
Sorry - I apparently put "T5250" in my earlier comment when it should have been "T7250" if you didn't notice. T5250 is another $100 off the price of the laptop, and would compete more against an AMD TL-50.BitJunkie - Friday, October 5, 2007 - link
Excellent, thanks for the reply.nitrous9200 - Friday, October 5, 2007 - link
AMD is improving on it's existing products but still can't touch Intel. You've still got some more work to do, guys.Another thing, I don't like macs but when I looked at the side profile view of the HP, I really though "ugh!" It's so thick and ugly looking. The manufacturers should start working on aesthetics just a little bit.

Performance isn't everyting only when you are not the performance leader :) Price/performance is pretty much the ticket, how you define performance may vary, but in mobile that is usually a convolution of computational prowess and battery life.
I am sure if, or when, Intel no longer holds the performance "heavyweight belt", then Intel will be the one who claims performance isn't everything and AMD will be droning home what performance is all about.
