To ensure proper cooling of the new Pentium Extreme Edition 840 processor, Intel offers a new solution with larger cooling surface and a larger copper sole. The picture below shows the old boxed cooler for top LGA 775 CPUs (left) and the new cooler for dual-core processors (right):
Throughout our tests the temperature of the processor working with the above mentioned new cooling solution under maximum workload didn’t exceed 70oC.
Testbed and Methods
During this test session we compared the performance of the dual-core Intel Pentium Extreme Edition 840 processor with against that of the tope single-core processors as well as against the top dual-core CPU from AMD. So, Pentium Extreme Edition 840 will be competing today with Athlon 64, Athlon 64 FX, Athlon 64 X2, Pentium 4 and Pentium 4 Extreme Edition.
For our tests we assembled a few systems. Here is a list of the hardware we used:
- AMD Athlon 64 X2 4800+ (Socket 939, 2.4GHz, 2 x 1024KB L2, E6 core revision aka Toledo);
- AMD Athlon 64 FX-55 (Socket 939, 2.6GHz, 1024KB L2, CG core revision aka ClawHammer);
- AMD Athlon 64 4000+ (Socket 939, 2.4GHz, 1024KB L2, CG core revision aka ClawHammer);
- AMD Athlon 64 3800+ (Socket 939, 2.4GHz, 512KB L2, E3 core revision aka Venice);
- Intel Pentium Extreme Edition 840 (LGA775, 3.2GHz, 2 x 1MB L2);
- Intel Pentium 4 Extreme Edition 3.73GHz (LGA775, 3.73GHz, 2MB L2);
- Intel Pentium 4 660 (LGA775, 3.6GHz, 2MB L2);
- Intel Pentium 4 570 (LGA775, 3.8GHz, 1MB L2);
- ASUS A8N SLI Deluxe (Socket 939, NVIDIA nForce4 SLI);
- ASUS P5ND2-SLI Deluxe (LGA775, nForce4 SLI (Intel Edition)).
- 1024MB DDR400 SDRAM (Corsair CMX512-3200XLPRO, 2 x 512MB, 2-2-2-10);
- 1024MB DDR2-667 SDRAM (Corsair CM2X512A-5400UL, 2 x 512MB, 4-4-4-14).
- PowerColor RADEON X800 XT (PCI-E x16) graphics card.
- Maxtor MaXLine III 250GB (SATA150) HDD.
