Last month"s price cuts not only made it tempting lớn build a new PC today, but they also brought quad-cores within the reach of mid-range budget systems.

For $266 you now have a tough decision lớn make: bởi you buy two 3.0GHz cores or four 2.40GHz cores? In our last đánh giá we found that if you"re doing any amount of 3d rendering or truyền thông encoding, the bộ vi xử lý core 2 Quad Q6600 at $266 ends up being the better value. Of course, if you want the best of both worlds you could always overclock the 2.40GHz Q6600, giving you four, much faster cores.

Hitting the S-Spec

In between major architectural revisions of processors, a chip core will go through multiple revisions or steppings. These steppings can be simple manufacturing tweaks, allowing for cooler operation, or they can include bug fixes & slight performance improvements. Performance improvements are rarely tangible, if even measurable in most cases, but the point is that these cores evolve over time. AMD & Intel learn better, more efficient ways to produce the chips over the lifetime of the processors và they incorporate the learnings into later revisions of the processors.

The original vi xử lý core 2 processors that launched in July of last year were stepping B1, they were later replaced by a B2 stepping. Hãng intel quietly introduced a new core with only 2MB of L2 cache (instead of 4MB with only half enabled), & thus we gained two more steppings: L2 & M0. The quad-core processors use a slightly different chip core stepping as well: B3.

More recently, intel introduced yet another revision lớn its core 2 microprocessors: the G0 stepping.

G0 fixes a handful of bugs, but most of them were minor & or have software workarounds in play. The more noticeable aspect of G0 is its lower power consumption, which some have proposed as meaning G0 cores may be better overclockers.

Only a subset of hãng sản xuất intel processors are presently available with G0 stepping cores: the chip core 2 Duo E6540, E6550, E6750, E6850, Q6600, Q6700, QX6800 và QX6850. Of those listed, the E6540, E6550, E6750, E6850 and QX6850 are only available in G0, while the remainder are offered in B2 or B3 as well.

How bởi you know what stepping you"ve got? CPU-Z will tell you exactly what you"re running, but you can also look at the CPU itself or the box it came in if you"ve got a retail chip.

Intel encodes the vi xử lý core stepping, cache size, frequency, package, FSB & more into a five character code called an S-Spec. You can use Intel"s Processor Finder to decode almost any S-Spec, although there are some limitations.

The new G0 stepping chips have the following S-Specs:

 S-Spec Core Stepping CPU
SLACQ G0 Q6700
SLACR G0 Q6600
SLAA5 G0 E6540
SLA9X G0 E6550
SLA9V G0 E6750
SLA9U G0 E6850


Here we have the new G0 based SLACR S-Spec on a processor box:


...and on the Q6600 itself:


Some vendors will even go as far as to hand select only G0 processors, advertising them as such. The question we"re here khổng lồ answer is whether or not the G0 based Q6600, (S-Spec: SLACR), is noticeably better than its B3 predecessor (S-Spec: SL9UM).
