Intel Processor upgrade: Intel Pentium D 840 Dual-Core 3.2 GHz LGA775 Socket L2 cache - 2 MB 800MHz FSB

The 915 is an good budget choice, but elsewhere this family is eclipsed by newer offerings. The Pentium D is something of a stepping stone in the world of CPUs: both a throwback to the days of gigahertz races and high TDPs, as well as the trailblazer

Overclocking As you saw from the results presented in the charts, we were quite successful in overclocking the 840 D. Our final stable overclocked speed was 4.04GHz, a massive jump from the stock 3.2GHz. What did we do? - used a watercooler to try and keep the processor temperature under control...

It's time for another processor review here at Neoseeker. This time we are taking a look at the Intel 840 D - a mid range dual core offering; we hope to look at its newer 65nm 940 brother in the near future. The 840 D has the following features: - 800MHz FSB - two 3.2GHz cores - one megabyte of...

Our test system consisted of the following: Intel 840 D: Intel Pentium 4 840 (Smithfield 3.2 GHz, 800 MHz FSB, LGA775) 2*512 MB Corsair XMS2 PC8000 @ 5-4-4-9-2T up to 1000 MHz Western Digital WD1200JD SATA hard drive 7800GTX 256 MB PCI-Express AMD 3800x2: DFI LanParty nF4 SLI-DR motherboard...

Business Benchmarks Disclaimer: the non-840 results were obtained with a different video card and driver; however the results should still be largely comparable as the 6600GT was an excellent 2D performer. Winstone 2004 This benchmark may be an 'Oldie' but I consider it to be a 'Goodie'....

Sandra CPU Test Disclaimer: the difference in video cards and drivers would not influence this test, and the results are directly comparable. As the Sandra CPU test uses both cores, the 840 beats the 670; however the 3800x2 beats the 840. Sandra Memory Test Disclaimer: the difference in video...

PLEASE NOTE: All of the gaming tests were run at 640x480 low details, no AA or AF as this is a processor review. In an upcoming article we will take a look at how this processor fares with high resolution gaming. Call of Duty Disclaimer: the difference in video cards and drivers would...

RightMark Read Disclaimer: the difference in video cards and drivers would not influence this test, and the results are directly comparable. The stock 840 is in the middle of the pack, with the overclocked 840 easily dominating the field. Looks like in this case the higher bandwidth of the DDR2...

LAME MP3 Disclaimer: the difference in video cards and drivers would not influence this test, and the results are directly comparable. The 840 does well for LAME. TMPGEnc MPEG2 Encoding Disclaimer: the difference in video cards and drivers would not influence this test, and the results are...

Sandra CPU Sandra CPU testing showed a basically linear increase with processor speed - the 26.875% increase in processor clock speed produced a 25.06% in integer results, 25.15% in fpu results and a 26.13% increase in SSE2 performance. Sandra Memory Increasing the FSB from 800MHz to 1160 - a...
