Conceptually, however, the Core 2 Duo E7200 is basically a Q9300 sawed in two: a Penryn-based dual-core with 3MB of L2 cache.
If you took a Core 2 Quad Q9300 and sawed it in half… Well, it wouldn’t work, and you’d totally be out a processor. The Core 2 Duo E7200: Cheap for the peeps At $316, it too may be a fairly compelling value.

This puppy has a full 6MB of L2 cache per chip and runs at 2.66GHz on a 1333MHz bus. Oh, and since we’re on the subject of 45nm Core 2 Quads, I’ve also thrown in some results on the following pages for the Core 2 Quad Q9450. The Q9300 will have to make its case against the E8500 on the strength of its two additional cores. This is a full-on Penryn dual-core with 6MB of L2 cache and a clock speed of 3.16GHz. If the competition from AMD isn’t trouble enough, the Q9300 also has to contend with a stable mate, the Core 2 Duo E8500, which also lists at $266. We’ll have to see whether the Q9300 can back up its price premium.
The Phenom 9850 Black Edition lists for about 30 bucks less than the Q9300, though, and has an unlocked multiplier to make overclocking easier. Intriguingly, that processor is also clocked at 2.5GHz and features a single-chip, native quad-core design with 2MB of 元 cache shared between all four cores. The Q9300’s closest competition from AMD is the Phenom X4 9850 Black Edition. Oh, and the Q9300’s TDP (thermal design power) rating is 95W, down from 105W in the Q6600, thanks to the magic of Intel’s high-k 45nm fab process. You’ll see what I mean when you see the Q9300’s performance results. The thing is, these days, caches are becoming large enough that we’re getting well into the realm of diminishing returns for larger caches, especially in common desktop applications. If not, then the difference may be zip, nada, nothing. If a program’s working data set is too large to fit into a 3MB cache but will fit comfortably into a 4MB or 6MB cache, then the difference may be pronounced. How much will the Q9300’s smaller cache size affect its performance? Well, like so many things, it depends. The Core 2 Quad Q6600 offered a 2.4GHz core clock, 1066MHz bus, and an older version of the Core microarchitecture for the same price. Factor in Penryn’s higher per-clock performance, and the Q9300 beats out its predecessor on multiple fronts. The Q9300 runs at a default 2.5GHz on a 1333MHz bus and lists at $266. But Intel’s willing to sell it cheaper that way. (Math is hard.) In the Q9300, however, each chip has half of its L2 cache disabled, so the processor has a two-by-3MB cache config, for a total of 6MB of L2. That gives most Penryn-based quad cores a total of 12MB of L2 cache. Each Penryn chip has 6MB of L2 cache onboard, dynamically partitioned and shared between the chip’s two cores. What makes the Q9300 distinctive is its level-two cache. In that sense, the Q9300 is really not much different from the Core 2 Extreme QX9650 introduced last October. The two chips operate more or less independently, communicating only by means of the front-side bus.
To create a quad-core processor, Intel groups two Penryn chips together into one package. The Q9300 is built from the same basic ingredient as Intel’s other 45nm processors: the dual-core chip code-named Penryn. The Core 2 Quad Q9300: Affordable four-banger As is our dubious custom, we’ve tested these two processors against a whole slew of would-be competitors and wholly inappropriate alternative options. The Core 2 Duo E7200, meanwhile, is Intel’s cheapest 45nm dual-core CPU and a potential goldmine of overclocking potential. The Core 2 Quad Q9300 is Intel’s most affordable quad-core processor, and it promises to supplant a long-time favorite of ours, the Core 2 Quad Q6600, by offering additional goodness at the exact same price. We have two of these chips on the bench today, and they’re just now becoming widely available.
We especially like the idea of budget 45nm Core 2 processors for yet another reason: they promise to combine a potent punch with modest power draw. We like budget processors for obvious reasonsthey’re cheap, like usand not-so-obvious onesthey tend to have the most overclocking headroom.

Two of the final steps along Intel’s path to 45nm ubiquity are of great interest to PC enthusiasts: budget dual- and quad-core processors. We first reviewed a 45nm Intel processor back in September, and since then, the CPU maker has been ramping up production and slowly transitioning to 45nm chips across its product lines.
