Intel Pentium D 820 Dual Core Characteristics
I am creating this FAQ to simply inform people of Characteristics of the Intel Pentium D 820 CPU....Enjoy!!!
I will now advise you of the characteristics of the Intel Pentium D 820 CPU in the table below (THIS IS AN EXAMPLE OF A CPU RUNNING AT 2.8GHZ)
Pentium D 820
Bus frequency:800 MHz
Typical heat dissipation:95W
Max. Typical case temperature:69.8Â°C
L2 cache size:1MB+1MB
Production technology:90 nm
Hyper-Threading Technology support:NO
Intel Extended Memory 64 Technology (EM64T) support:Yes
Execute Disable Bit Feature (NX) support:Yes
Enhanced Intel SpeedStep (EIST) support:No
Now something that I noticed immediately would have been the level 2 cache which in total is two megabytes, know I hear some people out there saying'' Yeah and so what ''. Well I will know explain, With 2mb of l2 cache this gives the processor much more freedom to process more information at anyone time and do it at a faster rate, but thatâ€™s not it because for all you Overclockers out there this 2mb l2 cache boasts a lot of overclocking potential because with the higher cache this give the processor more freedom overall to get those extra GHZ'S.But as a warning when overclocking a dual core you have too be careful about the operating temperature like in all cpu's but the dual core cpu is more likely to get hotter as there are now to physical cores now producing heat!!!.
The second Characteristic I noticed about the new PENTIUM D DUAL CORE CPU would be that it doesnâ€™t support hyperthreading and this is because to keep hyper threading would be unethical simply because with hyperthreading on it creates a second ''VIRTUAL'' cpu core, But with a Dual core cpu there is obviously no need for Hyperthreading as there are already two physical cpu cores.
Unfortunately when buying this processor you are limited to the motherboards you can have at this moment in time as this Dual core processor can only use the i955X or i945P/G based mainboards so please remember that when buying this cpu you have to have the right chipset or the cpu will not operate at all. Luckily an inbuilt feature in the Dual core cpu would be that if you were to put Dual core cpu into a non-compatible motherboard it wont cause any damage because it simply wont start up and this is because the Dual core cpu is designed to only recognise the i955X or i945P/G chipsets.
This Dual core CPU still only has an 800 MHz FSB as yet. But a higher fsb rating in the future for this type of Intel cpu is highly likely.
Now as you can see in the table above the typical heat dissipation is 95w.Now this is extremely high in comparison to other competitor CPUâ€™s like the AMD64 3500 which only dissipates 11.6w...Alot of difference when you think about it. So from this you can tell this Dual core CPU is rather power Hungary, so watch out when buying a new power supply unit.
Now the biggest thing that this CPU has to offer would be its extended ability to do 64 bit processing which puts Intel into a new league and into the world of 64 bit.
Well that just about wraps it up. If you have any questions then please feel free to PM me or EMAIL me. Also any suggestions are greatly welcomed.
