Summer hibernate IT industry. New products are expected only in the fall, and we have an opportunity, deliberately, let subtotals for 2007 in desktop processors. Let's start with the high-end - in this sector unchanged: only company Intel offers 4 - x nuclear processors, which provide three-fold increase in productivity optimized applications. True, this software still very rare, and the vast majority of programs downloaded only one CPU kernel.

Nevertheless, it could be argued that the dual-core processors today are the most balanced solution. First, they are accessible financially: both Intel and AMD offer models priced below $ 100. Second, the Windows operating system is multitasking: launch controller tasks, and you can see two or three dozen different processes, which are performed in "background" mode. This means that the running game, all these processes would not hinder her (and if they are, then very, very little).

The most productive company offers dual Intel processors. This is a different model of the kernel Conroe with 4 - x megabaytnym second-level cache and system bus frequency of 266 MHz and 333 MHz (QPB: 1066 MHz and 1333 MHz, respectively).

By the middle price categories can be attributed Conroe processors with 2 - megabaytnym L2 cache, and AMD processors masthead. In the lowest category includes Conroe-1M and other AMD processors. Moreover, there are budget category for which the company introduced Intel Celeron processors at a regular update kernel Conroe.

Celeron processors have always been phenomenal: Their performance was very low (it can be said there was no productivity!), But they bought only because without a central computer processor could not work! As a result, computer community, it is deserved, called the Celeron "to plug socket."

But now the kernel uses Intel Conroe-L, which is a modified kernel Conroe. Changes include: system bus frequency reduced to a minimum (200 MHz), as the volume of L2 cache (up to 512 KB). Secondary fact, in our view, reducing the number of processor cores from two to one. When testing processor E2140 and E2160 (both at Conroe-1M), we found that the reduction of FSB and L2 decrease resulted in a small decrease in productivity. If I continue to talk in this way, then we can expect from the new Celeron processor speed is decent work. To test this hypothesis, we bought the cheapest Celeron processor 420 with a frequency of 1.6 GHz for $ 44.

The utility depends on 512 Kb L2 cache memory and the frequency FSB = 200 MHz (800 MHz QPB). Meanwhile, the functionally kernel Conroe-L does not yield a senior fellow, and supports all advanced sets of commands, beginning and ending with MMX SSSE3 and EM64T. The same can be said of the support for C1E technology (Enhanced Halt State), and Execute DisableBit ThermalMonitor 2.

Regarding the physical parameters of the kernel, the operating voltage power supply is in the range of 1225 to 1325 W W, a typical level of heat equal to 35 W; kernel Conroe-L manufactured on 65 nm technological process.

To test was not unilateral, we acquired AMD processor. In fact, since the Conroe we obdelyali attention products of this company, because of the unattractive of "price / performance". But now, AMD has lowered prices, and as a single processor (at the price they catch with Intel Celeron) and the dual. To determine how competitive modern processors, we have acquired one of the cheapest dvuhyadernikov - Athlon X2 4200 +. Its retail price - $ 90; exactly the stands at Conroe E2140-1M.

It is not difficult to notice that the only difference in the presence of a second model of the nucleus of the 4200 +. Obviously, this fact has allowed AMD to increase productivity in the top 700 units.

Acceleration
Potential dispersal kernels Conroe-L was not so impressive as the kernel Conroe-1M, but nevertheless, we have reached a frequency of 3 GHz without special effort.
