我们都知道Windows Vista分为全新安装和从XP升级安装两种,微软也特别为后者提供了升级版本专用介质,而两种安装在性能上有何不同?升级安装对性能有多大影响?ExtremeTech为我们解开了这一答案---并没有多大影响.测试机型配置:
| Motherboard |
ASUS A8R-MVP (a sturdy and well-regarded CrossFire board) |
|
| CPU |
AMD Athlon FX-60 (it's a classic) |
|
| Memory |
2GB Crucial Ballistix |
|
| Graphics |
ATI Radeon X1900XTX CrossFire (Catalyst 7.1) |
|
| Audio |
Creative SoundBlaster X-Fi Fatal1ty (driver v.2_13_0001) |
|
| Storage |
Seagate Barracuda 7200.9 300GB |
测试项目:
- PCMark05—Default run.
(Note that this benchmark failed to run on the Vista upgrade. It simply
closed without so much as an error message, probably because of an
as-yet-undocumented incompatibility. Since this report is intended to
compare a Vista upgrade to a Vista clean installation, the results were
useless; we did, however, provide the results of the XP baseline tests
and the Vista clean installation test for the sake of curiosity.) UPDATE:
After many hours of fidgeting with Windows, uninstalling programs, and
searching deep for incompatibilities, we managed to get the benchmark
to run in the stripped version of Windows Vista. It simply refused to
run in the raw in-place upgrade. We're continuing our investigations—in
the meantime, the pertinent results chart has been updated.
- 3DMark06—Default run at low resolution (1024x768) and high resolution (1600x1200)
- Doom 3—Ran with default high quality settings at low res (1024x768) and high res (1600x1200, 4xAA).
- Half-Life 2Lost Coast—Run with default settings at low res (1024x768) and high res (1600x1200, 4xAA).
- Company of Heroes—Run with default settings at low res (1024x768) and high res (1600x1200, AA enabled).
- F.E.A.R.—Run with default settings at low res (1024x768) and high res (1600x1200, 4xAA).

Meanwhile, 3DMark06 tells us
that the light optimization we performed on the upgrade installation of
Windows Vista (i.e. the removal of background applets) doesn't do much
to affect this benchmark.
