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.

That's the P35 chipset. The article coldpower was pointing to is P965.. and he said modified his statement with "here", meaning "in the article mentioned".TA152H - Monday, June 25, 2007 - link
So you think that's relevant? People are going to buy 1333 FSB for the P965???? Again, are you crazy? P965 doesn't even support 1333 officially. P35 is what's important.zsdersw - Tuesday, June 26, 2007 - link
And besides.. the marginal improvement in overall system performance that P35 brings to the table doesn't prove or reliably suggest that Core 2 is particularly dependent on memory bandwidth or speed.TA152H - Tuesday, June 26, 2007 - link
You're seriously confused.Most of the information out now shows that you get pretty good performance with higher performance memory running at high clock speeds, especially for DDR3. It's now becoming common knowledge. But, they test DDR2-800 for some reason. To really see the performance of 1333 FSB, they should be using it with the proper memory instead of obsolete memory running at inadequate clock speeds. Luckily, there is another site that promised to do that in the very near future. Why they couldn't figure that out here is a mystery to me though, it kind of hits one in the face.

That's the expectation: higher performance with memory running at higher speeds. None of that suggests that Core 2's performance hinges upon extracting more and more out of the memory/chipset, though.zsdersw - Tuesday, June 26, 2007 - link
.. or, rather, that Core 2's performance depends on extracting more and more out of the memory/chipset.zsdersw - Tuesday, June 26, 2007 - link
All I'm saying is that you're barking up the wrong tree. coldpower's reference was to the P965, and then you started talking about P35 as if it had something to do with the results of the P965. They're separate.TA152H - Tuesday, June 26, 2007 - link
Are you unable to understand things in context?? Or are you arguing just to argue?The P965 is irrelevant, therefore his post is irrelevant, and therefore he has no point. The P965 doesn't matter for FSB 1333 processors, the P35 does.
My point was that they should be running memory at 1333 speeds, which means the P35. He brought up some nonsense that was irrelevant, and now you think that it was, and the P35 isn't. It's like the Twilight Zone.

No, my post is completely relevant, if your going to argue about official support on the P965 for 1.33GHZ FSB processors then DDR3-1333 is rejected to it being not officially supported by the P35 Express chipset, the only chipset to have official support for that is X38.If you need to prod others then I believe it's you who are the one that can't stand losing an argument.

An established chipset on which the Core 2 processors run is not irrelevant to the issue he was addressing: Core 2 performance vis-a-vis memory bandwidth/speed.
