Intel Core 2 Duo E6750 Preview: The Desktop Gets a 1333MHz FSB

By the end of Summer, Intel's Conroe lineup will have ballooned from a meager five processors at launch to at least different 14 models. The once simple model number system is now well on its way to being the complicated mess that plagued the P4's system before it.
First it was the introduction of the value E4xxx series, then the larger cache Exx20 series, followed by the even cheaper E2xxx CPUs and now the new 1333MHz FSB processors.
The new 1333MHz FSB CPUs will end in the number 50 (e.g. E6750), with the exception of the E6540 which is also a 1333MHz CPU. Although Intel isn't announcing pricing at this point, we don't expect the new 1333MHz FSB CPUs to cost any more than their predecessors; in other words, we expect the E6750 to carry the same price tag as the E6700 does. We've included the post July 22nd price cuts for the unreleased Intel processors in the table below (note that current processors will fall in price as well, although the table reflects present day pricing for currently available CPUs), as well as pricing for chips to be released in Q4:
| CPU | Clock Speed | FSB | L2 Cache | Availability | Pricing |
| Intel Core 2 Extreme X6800 | 2.93GHz | 1066 | 4MB | Now | $999 |
| Intel Core 2 Duo E6850 | 3.00GHz | 1333 | 4MB | Q3 | $266 |
| Intel Core 2 Duo E6750 | 2.66GHz | 1333 | 4MB | Q3 | $183 |
| Intel Core 2 Duo E6700 | 2.66GHz | 1066 | 4MB | Now | $316 |
| Intel Core 2 Duo E6600 | 2.40GHz | 1066 | 4MB | Now | $224 |
| Intel Core 2 Duo E6550 | 2.33GHz | 1333 | 4MB | Q3 | $163 |
| Intel Core 2 Duo E6540 | 2.33GHz | 1333 | 4MB | Q3 | $163 |
| Intel Core 2 Duo E6420 | 2.13GHz | 1066 | 4MB | Now | $183 |
| Intel Core 2 Duo E6400 | 2.13GHz | 1066 | 2MB | Now | $183 |
| Intel Core 2 Duo E6320 | 1.86GHz | 1066 | 4MB | Now | $163 |
| Intel Core 2 Duo E6300 | 1.86GHz | 1066 | 2MB | Now | $163 |
| Intel Core 2 Duo E4600 | 2.40GHz | 800 | 2MB | Q4 | $133 |
| Intel Core 2 Duo E4500 | 2.20GHz | 800 | 2MB | Q3 | $133 |
| Intel Core 2 Duo E4400 | 2.00GHz | 800 | 2MB | Now | $133 |
| Intel Core 2 Duo E4300 | 1.80GHz | 800 | 2MB | Now | $113 |
| Intel Pentium E2180 | 2.00GHz | 800 | 1MB | Q4 | $84 |
| Intel Pentium E2160 | 1.80GHz | 800 | 1MB | Now | $84 |
| Intel Pentium E2140 | 1.60GHz | 800 | 1MB | Now | $74 |
Intel sent out samples of its Core 2 Duo E6750 ahead of their scheduled availability as a preview (and probably to jab at its competitor a bit), so the processor we're previewing won't be available for a little while. Intel's internal roadmaps show Q3 as the timeframe to expect its 1333MHz FSB CPUs, but Intel's official statement is that these CPUs will be available "later this summer."

Keep in mind that AMD's pricing is keeping the company's lineup quite competitive with Intel below $300. You can buy all Socket-AM2 AMD processors for less than $300, resulting in great price/performance from the guys in green.
| CPU | Clock Speed | L2 Cache | Price |
| AMD Athlon 64 X2 6000+ | 3.0GHz | 1MBx2 | $241 |
| AMD Athlon 64 X2 5600+ | 2.8GHz | 1MBx2 | $188 |
| AMD Athlon 64 X2 5200+ | 2.6GHz | 1MBx2 | $178 |
| AMD Athlon 64 X2 5000+ | 2.6GHz | 512KBx2 | $167 |
| AMD Athlon 64 X2 4800+ | 2.5GHz | 512KBx2 | $136 |
| AMD Athlon 64 X2 4400+ | 2.3GHz | 512KBx2 | $121 |
| AMD Athlon 64 X2 4000+ | 2.1GHz | 512KBx2 | $104 |
| AMD Athlon 64 X2 3800+ | 2.0GHz | 512KBx2 | $83 |
| AMD Athlon 64 X2 3600+ | 1.9GHz | 512KBx2 | $73 |
Note that AMD will respond with its own set of price cuts in late July to keep the landscape competitive after Intel's cost cutting measures.

Cool, so basically my E4400 oc'd to 3.0GHz @ 1333MHz fsb is essentially an E6850 with half the L2 cache (2MB vs 4MB). For only $135 it's giving me quite the bang-for-the-buck. :DJmsAndrsn - Monday, June 25, 2007 - link

sorry, forgot to mention i dropped the multiplier to 9x. =)Not enough heatsink to cool 3.3Ghz to a temp i was satisfied with.

Slightly off topic, but since the 1333 FSB has 10.6 GB/s bandwidth (1333 x 64bit) I can use DDR-667 in dual channel mode(also 10.6 GB/s[667 x 128 bit]) without any performance hit right?bamacre - Monday, June 25, 2007 - link
Yup. At stock speeds you'll only need 667mhz DDR2 for the 1333mhz FSB C2D's. And of course 533mhz DDR2 for 1066mhz C2D's.gigahertz20 - Monday, June 25, 2007 - link
Gary Key,I've been waiting for your promised P35 roundup article you mentioned in your May 30th "Gigabyte GA-P35T-DQ6: DDR3 comes a knocking, again" article. Any word on what day this week it will be posted? I'm eagerly waiting the release of the article so I finally buy my long awaited Core 2 Duo setup, I just need a solid motherboard to go with it.

If you give up waiting, go for the MSi P6N-SLI Platinum. Awesome 650i-SLI board. She's rock solid for me @ 1333MHz fsb, only voltage increase is on the vcore, and I'm running 4GB dual-channel paired in the four DIMM slots. Fast and stable, just as I'd wanted.gigahertz20 - Monday, June 25, 2007 - link
Is the article on time to be published this week?Deusfaux - Monday, June 25, 2007 - link
I assume your comparisons of the 2 FSBs are keeping end clock speed the same?sc3252 - Monday, June 25, 2007 - link
Why don't your new articles have tests where you run multiple applications at the same time, I really enjoyed reading older articles how the cpu's stood up to multitasking. Its nice that we have benchmarks showing how much faster the new cpu's are, but I don't think it shows how we will really be using the computer.For example I will be using my computer much different then say playing one game strictly. When I play world of warcraft I will usually have itunes open playing a song, and Firefox open looking up where to turn in my next quest. It would be nice if in future articles you could create a benchmark doing some of those things.
