Intel Core 2 Duo E6750 2.66 GHz 1333MHz FSB Processor Review
Intel Core 2 Duo E6750 2.66 GHz 1333MHz FSB Processor Review - PCSTATS
If you haven't already heard, Intel recently injected fresh life into its Core 2 Duo Conroe platform by increasing the front side bus speed from 1066 MHz to 1333 MHz.

Boosted to 1333MHz, E6750 Kicks up Dust!

The Intel Core 2 Duo is easily the best desktop processor architecture available on the market. Team that up with ramped up front side bus speed (now kicking away at 1333MHz), very very aggressive pricing, average ~65W for CPU energy consumption, and well... it's no surprise Intel is slaughtering AMD.

Officially the Intel Core 2 Duo E6750 is a higher end processor model, with a default clock speed of 2.66 GHz and 4MB of on-die L2 cache. It's retail price is another mather though, and more in tune with an entry level CPU. I don't know how Intel can get away with only charging $218 CDN ($206 US, £103 GBP) for the Core 2 Duo E6750... The E6600 cost more than twice this when it was introduced. In any case, as PCSTATS full set of benchmarks have shown you, the E6750 CPU really packs in a lot of value! Nice.

On the technological front there is no significant difference between the Intel Core 2 Duo E6750 and earlier Core 2 Suo versions. Manufacturing die technology, L2 cache sizes and core architecture remain identical between the Core 2 Duo E6750 and E6600 which runs on a 1066 MHz FSB.

The new 1333MHz FSB chip simply uses a newer core stepping and runs on a higher 1333 MHz Front Side Bus. With that said, though if you want one of Intel's new 1333 MHz parts for yourself, you'll need a new Core 2 Duo compatible motherboard or at least something based on Intel's P35 Express, G35 Express, G33 Express of nVIDIA's nForce 6 series (680i, 650i) chipsets.

The Core 2 Duo E6750 has a TDP of 65W which is considerably lower than the old Pentium D's consumed. Total system power draw tests showed us than an E6750 can be the cornerstone of a more energy efficient platform, particular when compared to the Pentium D 940 and Athlon64 FX-62 systems which consumed upwards of 168W each. The Core 2 Duo E6750 system weighed in at 123W.

Under a multi-threaded load, the differences in power consumption ballooned. The Intel Core 2 Duo E6750 CPU system drew 151W with one core loaded, and 163W with both processing cores stressed. The Pentium D 940 was the worst offender - it managed 230W and 253W respectively for single and dual core loads. Even AMD's Athlon64 X2 5000+ CPU system was poor; consuming 177W with a single core load and 207W with a dual core load.

The Intel Core 2 Duo E6750 processor really excelled in all the benchmarks.

Office applications underlined the point that the E6750 is overkill for these kinds of tasks, an economical CPU handles the benchmarks at almost at the same levels. When it comes to 3D gaming or data crunching software, nothing else matched the Core 2 Duo E6750 processor! You can tell that the 1333 MHz FSB made quite a difference, for the 1066MHz FSB Core 2 Duo E6600 had a difficult time keeping pace.

The big question PCSTATS really wanted to answer is whether the Intel Core 2 Duo E6750 CPU would run better with low latency DDR2 memory or with DDR3 RAM? The latter has a huge amount of memory bandwidth, which will benefit quad core processors more. Reading between the lines, Intel is basically trying to lay the foundation for quad core processors, that's why DDR3 is available now. As you saw in the benchmarks, the dual-core Intel Core 2 Duo E6750 processor runs best with low latency DDR2 memory, there's no reason to upgrade to DDR3 with this processor.

The coolest thing about the new 1333MHz Intel Core 2 Duo processors like the E6750 is its overclocking capability! The previous Core 2 Duo CPU generation could reach 3.4-3.6 GHz without much difficulty, but the new 'G0' stepping can do even better. The Intel Core 2 Duo E6750 PCSTATS tested was able to hit a spectacular 3.8 GHz while the stock Intel heatsink. We've already read reports online of other benchmarkers who have achieved close to 4 GHz on air cooling!

If you're in the market for a new processor or want to overhaul your system, now is an excellent time. The 1333MHz FSB Intel Core 2 Duo E6750 processor is an awesome CPU, and it is dirt cheap for what it can accomplish on a P35 Express motherboard with nice (affordable) low latency DDR2 RAM!
