Dual-core Pentium D 805 (Smithfield)
Introduction
Late last year, a critical situation shaped up on the market
of desktop processors. Because of missed supplies of AMD's lower-end
processors, prices on them went up immensely, almost twice as much.
That resulted in the rise of prices for Intel processors, albeit not
that high. But in March this year prices for Athlon 64 3000+ and 3200+
stabilized and now they can be made available at 3200 rubles (~$115)
and 3600 rubles (~$130), respectively. Prices for Intel processors
remained unchanged: the 6õ0 line still sells at quite a high amount, P4
630 - at 4700 rubles (~$160), P4 640 - at 5600 rubles (~$200). As a
result, if contra-posed, the produce by AMD offers substantial price
advantages, lower heat emission level, and higher performance at games.
Absolutely reverse situation shaped up on the market of
desktop dual-core processors. As before, Athlon64 X2 3800+ is still
AMD's younger model which is available at 9000 rubles (~$320), whereas
Intel offers Pentium4 920/930 at quite affordable 6600/6800 rubles
($235/$240). The Pentium 9x0 line is based on the new Presler
core which features in a relatively new level of heat emission and
superb overclocking capability. The low price is definitely not enough
for a convincing victory, but at least it can make the user think twice
before making a purchasing decision.
According to Intel's plans for aggressive promotion of
dual-core processors, for the recent months the company has released a
very interesting model - Pentium D 805. It is based on the Smithfield
core (1 MB of L2 cache per each core), runs at 2.66 MHz, and the system
bus speed is 133 MHz (533 MHz QPB). This processor did not arouse much
interest but only until it hit the retail at 3700 rubles (~$125) for
the OEM version (versus 4000 rubles (~$135) in the BOX version). As a
result, the processor simply has no direct competitors and we can state
that it has created a new market of dual-core low-end systems.
Pentium D 805 processor
The processor is packaged in a box of the following form:
The user can get a complete information on the processor from
both the box cover
and the marking of the processor which is seen through a
transparent window in the upper part of the box.
Externally, the processor doesn't make any difference from
other LGA775 models.
On the reverse side, Pentium D 805 has the same positioning of
capacitors as in the processors of pervious steppings of the Smithfield
core:
As you can see, the processor in question is based on a new
stepping of the Smithfield core - F47 B0 (remember that the first
Smithfield processors were based on the stepping F44 A0).
Therefore, we can expect some improvements in power
consumption and overclocking. In fact, it's just overclocking we are
most interested in since the lower-end models of processors show the
best results at that and allow for improving the system performance
substantially, and to save some money on that.
