Part One: Introduction
Today's Pentium 4; a whole lot different to the original
CPU launched some time ago and received with mixed feelings.
Developed around the controversial Rambus memory, users
either loved the Pentium 4 or they hated it. AMD's updated
Athlon was performing better in some benchmarks despite
running at a far lower clock speed while still retaining
a reasonable pricing structure. Something had to change;
indeed it has... and how! We are receiving many reports
that the true performance crown belongs once more to Intel
and their updated Pentium 4's. With a friendly outlook for
DDR memory fans and a shift to a quad pumped 133 FSB the
Pentium 4 is back with a bang! We were interested just how
load that metaphorical bang was... so therefore, here it
is; AMD's current top CPU vs Intel's fastest Pentium 4.
Have Intel smashed through the performance levels offered
by AMD? Let's find out...
Part Two: The Pentium 4
Here are the main features offered by this new CPU, in
truth not much has changed since we looked at the 2.2GHz
'Northwood' update in March.
If you need a closer look at the CPU then take a closer
look at that report here.
This table featured in the aforementioned review,
I've updated it so you can clearly see how the new Pentium
4 line up against their older relatives.

Intel Net Burst Micro Architecture: -
- 533 or 400 MHz system bus
- Hyper-pipelined technology
- Rapid execution engine
- Execution trace cache
- Advanced transfer cache
- Advanced dynamic execution
- Enhanced floating point/multimedia
- Streaming SIMD extensions2
From the tabular data above the important
features to highlight are firstly the voltage decrease,
1.50V is now the default voltage for all Northwood 'A' and
'B' CPU's.
Secondly the L2 cache increase from the original 256K to
the 512K of the latter CPU's.
Thirdly, on these new CPU's, the System Bus has increased
from 100MHz to 133MHz QDR. (400MHz - 533MHz effective)
Next the transition to Socket 478 only.
Lastly the standard .13 Micron presentation now utilizing
copper interconnects.
So in summary: Northwood A's run on the 400MHz
FSB while these newer Northwood B's are using the newly
introduced 533MHz FSB.
It's worth also noting that the new version
of Intel's RIMM supporting motherboard, the i850E, still
doesn't official support 1066 Rambus. We can only speculate
the relative scarceness of such memory is a contributing
factor here. I wouldn't suggest it's part of the shift from
Rambus to DDR memory at this stage. We have reason to believe
Intel will be supporting both memory types in the
future which is pleasing for the enthusiast to whom bandwidth
is everything! I'm personally a great supporter of Rambus
memory, we shall investigate this later in the review.
Further information can be found at Intel's
website
and as mentioned above, our past Pentium 4 reviews.
We will take a look at the CPU on the next page and then
it's straight into the benchmarks...
