AMD Phenom II X4 905e 

Released June, 2009
  • 2.5 GHz
  • Quad core
4.5 Out of 10

In most other areas, the 905E's performance is predictable, which is to say solid if hardly spectacular.

In raw performance terms, this chip would certainly make for great small form factor system.

Reviews Word on the street for the AMD Phenom II X4 905e


6.0
The 905E also clocks up better than the 610E, hitting 3.9GHz.

What People Are Saying Give it to me straight

Power

For a chip that trades on efficiency, the AMD Phenom II X4 905E's results in our platform power consumption tests are ugly.
by Tech Radar (Sep, 2010)
Firstly, full motherboard support is required to get the best out of these low-power processors.
by Tech Radar (Sep, 2010)
Judging the Phenom II X4 905E's power consumption is tricky without proper motherboard support.
by Tech Radar (Sep, 2010)

Socket Type

As it is, we can't comment on the 905E's low power credentials.
by Tech Radar (Sep, 2010)
Like its Athlon II X4 610E sibling, the 905E is a low-power variant of a familiar AMD processor.
by Tech Radar (Sep, 2010)
However, it's also rated at 65 Watts.
by Tech Radar (Sep, 2010)

Price

We'd go with the cheaper chip.
by Tech Radar (Sep, 2010)
For a price, the AMD Phenom II X4 905E promises to make all that possible.
by Tech Radar (Sep, 2010)

Multicore

You therefore get all four cores and the full 6MB of L3 cache memory.
by Tech Radar (Sep, 2010)

Gaming

It's a little slower for video encoding but quicker at professional 3D rendering, gaming and file decompression.
