Intel Core i7 Mobile processors draw a 30% more power than Core 2 ones

Monday, October 26th, 2009

Finally! Somebody has performed a power consumption comparison between Intel Core i7 processors for laptops and Core 2 ones in similar configurations. The conclusion: a Core i7-920XM draws a 32% more power than a Core 2 Extreme QX9300 when idle, a 24% when playing a DVD. The performance benefit is ar0und 20% (between 0 and 36%, in general), so the efficiency of this new processors is not impressive. It would be very interesting to see data from the non-Extreme processors, but the results would be probably similar.

Is Alienware preparing a 23-inch laptop?

Thursday, October 22nd, 2009

I seriously doubt it, but a Dell agent at the Dell US Chat seems to have mentioned a 23-inch Alienware laptop to be announced in a month or so. It could be only an attempt to distract the customer. In addition, I can’t think about many reasons to need such a big laptop (well, maybe using desktop graphics cards). The biggest ones I have seen are 20-inch, and they were really huge, anything bigger would be mad.

AMD Turion II M500 performance: it scores 5.7 in WEI (Windows 7)

Thursday, October 22nd, 2009

The Windows Experience Index (WEI) is not a very informative benchmark but at the moment it is the only indication of its performance that I have found. Today I have found an HP Pavilion dv7 laptop with Windows 7 and an AMD Turion II M500 (2.2 GHz) at a mall. I have quickly looked for the system properties and the WEI: the CPU subscore was 5.7; next to it there was a dv6 laptop with an AMD Athlon II M300 (2.0 GHz): it scored 4.9.

Some scores of Intel processors to compare (collected from the Net or from other Windows 7 laptops in the mall):

  • Intel Pentium Dual Core SU4100 (1.3 GHz): 4.0
  • Intel Pentium Dual Core T4300 (2.1 GHz): 4.9
  • Intel Core 2 Duo T6600 (2.2 GHz): 5.5
  • Intel Core 2 Duo P8600 (2.4 GHz): 6.0
  • Intel Core 2 Duo T9600 (2.8 GHz): 6.4

So it looks like the new AMD Turion II and Turion II Ultra are going to compete in performance against mainstream Core 2 Duo processors, not high-end ones, but we need more benchmarks!

Update: according to PC Magazine, the AMD Turion II M520 (2.3 GHz) scores 4746 in Cinebench R10 (multi). That’s just in between an Intel Core 2 Duo P8400 2.26 GHz (that scores 4687) and a P8600 2.4 GHz (that scores 4856) and confirms the performance level.

Update 2: from the reviews of laptops with Turion II processors, it seems that the M500 is closer to a T6600 than to a P8400 or similar.

ATI Mobility Radeon HD 4870 in the Alienware M17x is GDDR3 instead of GDDR5

Thursday, October 22nd, 2009

It seemed some kind of typo because in some countries it was stated as being GDDR3 and in some others as GDDR5, but at the moment all the users that have got their M17x with CrossFireX 4870s have GDDR3 modules on it.

Performance data is very scarce at the moment, but it seems that the performance of the 4870 GDDR3 CrossFireX is very close to that of the GTX 280M SLI. If the ATI configuration is cheaper than the Nvidia one in your country, that’s OK.

Update: Dell has confirmed they are GDDR3. GDDR5 memory seems to generate too much heat.

Sony Vaio X reviewed: is it worth 1499 USD? (Laptop Magazine)

Wednesday, October 21st, 2009

It’s sexy, expensive and very, very light. But is it worth 1499 USD? The guys at Laptop Magazine have reviewed the Sony Vaio X and they have mixed feelings about it. If you are considering one of these ultra-light laptops, have a look at the review.

New Apple Macbook: still plastic, but Unibody

Tuesday, October 20th, 2009

The white plastic Apple Macbook has been updated. It is still made of white plastic, but in a single piece like the Unibody Macbook Pro. Other interesting updates are the LED screen and the multitouch-enabled trackpad without visible buttons. The battery is non-user replaceable battery and promises around 7 hours of battery life (and it probably delivers), but the port selection is rather limited: only Gigabit Ethernet, Mini DisplayPort, 2 USB 2.0 and a single audio in/out. The processor seems to be an Intel Core 2 Duo P7550 (2.26 GHz, 3 MB L2 cache, 1066 MHz FSB) with DDR3 RAM and the graphics card is the Nvidia GeForce 9400M.
