The Phenom II X6 is happening to us today is very similar to Phenom X4 II, except that it therefore has two extra core. You can stick to 128 KB of L1 cache and 512KB L2 cache per core, shared L3 cache and a 6 Mo. cons die through 258 mm to 346 mm, and the number of transistors 758,000,000 904 million, and everything remains engraved in 45nm. Here you can see two X6 with a TDP of 95W, a 1055T and 1035T (2.6 GHz / 3.1 GHz TC) but they are a priori reserved to OEMs. 1075T version running at 3 GHz with a 3.5 GHz Turbo mode is a TDP of 125W is scheduled for the third quarter, and a Phenom X4 II 960T clocked at 3 GHz with 3.4 GHz Core Turbo is actually a Thuban with 2 core disabled. Most attention will have noticed the TDP content of these processors despite a fine engraving in 45nm and the presence of 6 core. The Phenom X4 II 965 and 955 for C3 show a TDP of 125W reminder to 3.4 and 3.2 GHz, 95W cons for the 945 and 925-3 and 2.8 GHz.
You could see in the list of processors, they are equipped with a technology called Turbo CORE AMD. AMD's true answer to Intel Turbo Boost, this technology works like the latter automatically, without requiring software or driver is: only a compatible motherboard will be needed, what will happen to all maps AM3 but also a priori certain AM2 +. In practice, when three or more core are inactive cores active frequency will increase to 500 MHz by 400 to see the CPU, within the TDP. What about tension? We could do with the AMD OverDrive utility that the latter could vary. Thus, our Phenom X4 1090T Test II, when the turbo went up to 3.5 GHz in some hearts, they were still supplied with 1.3V, but went up to 1.475 V when the maximum of 3.6 GHz.
All bios motherboards do not include necessarily the ability to disable the Turbo Core, as is the case on Crosshair Formula IV with 0602, but in all cases the AMD OverDrive utility provides this possibility. Better still, it can also change from top to bottom: number of cores amplified maximum coefficient and are therefore modifiable DIT. When one core is active, its frequency varies between 3.5 and 3.6 GHz. With two core assets, we are at 3.5 GHz, with three cores at 3.5 GHz and with four core Turbo is inactive, resulting in a frequency of 3.2 GHz. It should be noted that AMD OverDrive does not re exactly the same frequencies as in the software it is AMD 3.6 GHz with 1 or 2 core and 3 core with it varies between 3.5 and 3.6 GHz. It is impossible to say now which of the software is right, but in any case we can see that the Turbo CORE is functional.
In comparison, our Phenom X4 II 965 Black Edition is 1.4V to review C2 and C3 1.35V review. The operating voltage is limited evidence of good joint working and AMD Phenom on GlobalFoundries II X6 revision E0. Of course it can vary from one processor to another and we have such knowledge of copies that have a VID of 1.325 v. According to its TDP Phenom II X6 1090T is relatively economical and configuration displays support only 7W more compared to a Phenom X4 II 965 in C3 review. If one remains at rest over at the top of this platform offers the Intel LGA1156, it is below the LGA1366. Here consumption measured on the ATX12V which feeds exclusively processor.
AMD will initially launch three models in this new family of six-core microprocessors, particularly the models are: Phenom II X6 1075T with a TDP of 125W, Phenom Phenom II X6 II 1055T and 1035T with a TDP of 95W (apparently there will be a version of the 1055T 125W) all 9MB cache.
The letter T in the trade name of the processor indicates the arrival of the turbo mode for AMD. The principle of this technology could not be simpler, if the processor finds that half of its cores are used and the heat generated is not too high, it will increase its frequency temporarily. The turbo mode is variable depending on the processor, as you can see from the table above can climb the 1090T 400MHz (3.6GHz in total) and of 500MHz 1055T (for 3.3GHz total).
The advantage of this feature is clear, at present there is still a good number of applications unable to take advantage of multicore processors, they will benefit more than a higher frequency of execution, that the presence of additional core, loading only work on one of processor core. In these situations turn off unused cores helps to contain the energy required by the CPU, part of which can be used to overclock the core under load, raising its frequency but keeping the total consumption by a maximum TDP. Thus consumption would remain unchanged (or even lower), whereas the benefits, both with applications optimized for multicore, which would remain high.
AMD Overdrive software has also been updated for the release of these processors and can therefore see the turbo mode in action. You can affirm that we now have not been seduced by the real application of the turbo mode. It is readily seen on the video but when three hearts are loaded (via SuperPi three transfers in parallel), we stayed at 3.2Ghz processor, even when both cores are requested, and however we see the CPU raise the frequency. But the 3.6GHz have actually been achieved very little time, we still managed to take a snapshot of the CPU-Z beast.
The influence of the turbo mode can the Cinebench R10 benchmark quite clearly visible: This benchmark takes the same test only one both core and with all available cores by using and shows much faster the use of multiple cores is like. For common Quadcores is known as the "speedup" is usually at 3.6 to 3.8 and slightly lower than the number of cores. Accordingly, the speedup in the vicinity of 5.4 to 5.8 is expected. With the turbo mode thread is the benchmark with only one accelerated, however, so the speedup is only 4.6. This represents a performance per core of about 21%, the right to bar increase of 18% fits well.
The Phenom Turbo II X6 Core technology comes into operation as soon as three or more cores are unused, and is anxious to overclock the core assets by increasing the frequency up to 500 MHz over the standard. The other core, those "sleepers" are instead taken to the minimum frequency of 800 MHz. Intel's approach is more sophisticated: Turbo Boost is activated regardless of the number of cores idle, and is able to take into account more factors including the overall workload. Thanks also to the technique of power drain, Turbo Boost can vary the voltage of each core independently from the others, and come to completely turn off unused cores: this provides a greater margin for overclocking the core assets.
