Thread: Intel E2140 and E2160 on the kernel Intel Conroe-1M

CPU on the kernel Core 2 Duo dramatically changed attitude to the user productivity and heat release. However, the first models were to the average (from $ 200) and the higher class (Quad). U buyers of low-cost computers had little choice: either AMD processors, or low-cost (but slow and hot) with the Intel NetBurst architecture. In summer 2007, the situation changed dramatically: Intel produces cheap (less than $ 100), dual-processor architecture with Core 2 Duo. Their job is not different from the frequency of senior processor (1.6 GHz - E2140; 1.8 GHz - E2160), and made cheaper by reducing the amount of cache memory of the second-level (L2) and reducing the frequency of the system bus. Thus, Intel avoided the internal competition between its processors and has made clear separation products. In particular, high-performance processor niche occupied by various Quad model; below are dual processors with a memory cache L2 = 4 Mb (E6xxx series). Processors have two mid-level kernel, but the amount of L2 reduced to 2 Mb (E4xxx series). And finally, the cheapest dual-core processor L2 = 1 MB (E2xxx series).

This structure is a pair of exceptions: E6300 and E6400 processors have L2 cache and 2 MB = frequency = 266 MHz FSB. A new high performance processors shifted to a FSB = 333 MHz. For more information see the Intel processor can range from our reference material

Reducing the frequency of the system bus to 266 MHz and 200 MHz should not disturb computer enthusiasts, but rather to inspire. To achieve relatively low clock frequency (for example, 1.6 GHz), Intel engineers had to increase the CPU multiplier (respectively, to eight). And, in combination with significant potential nucleus (3 GHz and above), this will be achieved impressive results in the dispersal. And while the resulting frequency FSB remain within reasonable limits (350-400 MHz). This will enable use to disperse a large number of motherboards, which are stable in that range.



In our testing, we talk two interesting question: to what extent the reduction L2 cache and FSB frequency reduction affected the performance of new processors. The second question - how well the new scalable performance with increasing frequency processor system bus. In other words, any increase in productivity will receive a user to disperse E2 series processors xxx?
From the external side - nothing special: as belonging to a series of processors E2xxx, said only marking. But on the back of a new series of processors easily determined by the number and location of capacitors:
The utility depends on the 1 Mb L2 cache memory and the frequency FSB = 200 MHz (800 MHz QPB). Also, we see stepping core "L2", but how it affects the payload capacity - yet unknown (too few statistics). Also worth paying attention to the kernel supports all advanced sets of commands beginning with MMX and ending with the most modern SSSE3 and EM64T. For this part series E2xxx equally functional, as a senior (eg E6xxx).

On other parameters E2xxx series processors also did not concede a senior fellow. In particular, they support technologies such as C1E (Enhanced Halt State), Intel SpeedStep, Execute DisableBit, ThermalMonitor 2 and virtualization.

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 65 W; kernel Conroe-1M manufactured on 65 nm technological process.



Acceleration
As we had anticipated Conroe processors on the kernel-1M showed impressive payload capacity. In particular, the model E2140 absolutely worked steadily at a frequency of 3.46 GHz,

In both cases, we used air cooling; Vcore voltage = 1.4 V. In other words, we can argue that Conroe processors-1M quite easy to disperse, but the end result depends exclusively on the characteristics of a specific instance.
