Turion 64 vs. Pentium M on Compaq v2000z and v2000

Threaded View
I'm planning on buying a Laptop and I'm facing a very difficult
choice: Should I go with AMD's Turion 64 or Pentium M ?

I really like the idea of having a 64bit system so I will be able to
upgrade in the future (my laptop has to last at least 3 to 4 years), on
the other hand I hear that the Turion64 drains much more juice from the
battery than the Pentium M. I'm trying to find out if it is possible
to find a balance between in having the 64bit upgradeability of the
Turion64 and a good battery run time.

I am looking at the Compaq v2000z (Turion64) and the Compaq v2000
(Pentium M). Does anybody have any battery run time data/comparison
from these machines? Would I be losing a lot of battery time if I get
the v2000z (Turion64)? I would like to have some user impressions from
these machines, specially the Turion64 as it is harder to find info
about it on the net.

I already looked at this review:
http://www.notebookreview.com/default.asp?newsID=2455 , but I would
like to have more info about it.

The Turion and the Pentium M are very close in terms of power consumption
so go with the Turion.

That's not the whole story though.  The processor is only one power
consumer.  Intel has taken some pains to put together a chipset and
peripherals to match the low power consumption of the Pentium M while AMD
has concentrated on the processors and left the chipsets to third parties.
Far as I know there aren't any AMD64 chipsets optimized for low power, so
even if the power consumption of the processors is the same the power
consumption of the machine as a while may higher for the AMD.

In terms of features, Turion offers x86-64 (64 bit) support, which will
increase both performance and offer "future-proofing" when Microsoft Vista
is released in 2006. In terms of price, a Turion-based laptop can be
hundreds of dollars cheaper compared to a similar Dothan-based laptop. In
terms of performance, Turion wins a majority of the non-synthetic benchmarks
in all categories, although the Pentium M is no pushover. In the third
category, battery life, Dothan wins when both processors are performing
CPU-intensive tasks. However, when doing light tasks such as word processing
and internet browsing, Turion is yet again the victor. The area where the
Pentium M really shines is during heavy load while running from the battery.
In most categories, the Turion meets or exceeds Pentium M's performance at a
lower price point.

When making your own decisions about platforms, it is important to keep in
mind that there are few available Turion-based laptops compared to the
countless Dothan-based laptops on the market. And even though Turion overall
was superior, Dothan is no slouch either. Although the Pentium M lost most
of the benchmarks, it trailed behind by a mere 5% or less most of the time.
Its efficient architecture means that even when performing the most
strenuous tasks, battery life is guaranteed to be long. x86-64 (64 bit)
support is still not necessary, as a 32bit version of Microsoft Vista will
also be released. Don't feel pressured to choose Turion if the machine doesn
't have the features or options you want: Intel's Pentium M processor will
also satisfy most user's needs very well.


Despite our new test results, things are even more un-clear than before.
Sure, we have concrete results that have been verified and re-verified. We
know for sure that Dothan is SLIGHTLY better on battery life and that Turion
is SLIGHTLY better performing (in most cases). But these results leave the
"winner" of this architectural comparison even more vague. Our final
decision for Turion 64 still stands, but not because it "beat" Dothan or is
supremely better than Intel's Centrino platform. Turion 64 offers equivalent
or better performance, very comparable batter life, and a lower price tag
(in most situations).

Our original hypothesis about Turion was that it would be more power
efficient under idle usage circumstances, like the Life test in Winstone's
BatteryMark test. Since the Life test consists of running common
productivity applications with timed periods of idle-ness to simulate true
user interaction, Turion's architecture lends itself to being more
efficient. First, the power ratings between Dothan and Turion cannot be
directly compared. A lot of people see Dothan's 27W TDP & Turion ML's 35W
TDP and assume that Dothan is automatically lower power. Intel computes
thermal design power as 75% of the maximum load on the chip, while AMD's TDP
rating is derived from the absolute worst case power dissipation of the
chip. Part of the total system power is also incorporated into AMD's TDP, as
the memory controller is located on-chip. Intel's memory controller is built
into the chipset and thus draws power not calculated as part of Dothan's
TDP. Also while Turion 64 is at idle (1GHz clock speed), it's performance is
going to be higher due to the higher clock speed and higher bandwidth data
bus. All of these factors contribute to Turion 64 being more power efficient
under low load circumstances.

Dothan, on the other hand, has an advantage under heavy CPU loads like the
Winstone BatteryMark Conditioning test. The Front Side Bus, Level 2 Cache,
WiFi card, and numerous other aspects of the Dothan architecture and chipset
are heavily power optimized. Certain parts of the L2 cache deactivate when
not in use, buffers used to store data for the FSB are powered down when
idle, and the wireless card automatically throttles power based on network
load. The Centrino platform has the advantage of the entire platform being
developed from the ground up for maximum performance and minimum power
consumption. Turion 64 has the advantage of a highly efficient, mature
architecture that lends itself to high performance per watt, although not
due to heavy power optimizations.<<

i've had one that lasted that long and a used one that must be about
that old now. it's a thinkpad 560z.

64bit doesn't mean much unless you have a buttload of ram.  can you
put 4gb in these laptops?  and, considering the expense and battery
drain, do you want to?  if not, it's not worth worrying about.

I guess you know nothing about Turion at all, do you?  and who said you need
4G of RAM to run 64 bit OS!

Maybe the os and cpu doesn't require 4g of ram, but I might have other
reasons for wanting it.  Most laptops I've seen have a 2g limit or lower.

Also, every Turion laptop I know of uses the xpress 200 video chip,
which has a secret interface, not good for us Linux users.

I have been pondering over the same question for some time now but
have just taken the plunge and got an Acer aspire 5024WMLi which is
Turion based.  All I can say is I feel I have made the right choice -
it is by far the fastest laptop  I have ever used - it copes with my
digital video editing with ease and this is probably the most
demanding thing I will ever use it for - and battery life is
sufficient for me at around 3 hours.

In my opinion - the Turion based systems are beter value for a given
