Market is the fourth generation Intel Core family
On the first day of June, the Intel Haswell series was officially launched.
The American processor giant is going through exciting times. Thanks to the Tick-Tock development schedule, the main rival AMD has been thoroughly overtaken so far, but in the meantime new trends have emerged and new opponents have emerged. There are a number of signs that the mobile era has come to the fore in development - perhaps in second place may be the integrated graphics processor.
There are very few points where the Intel Haswell family can be attacked, but overdrive still falls into this category. The integration has now reached a level that can cause difficulties in overclocking the CPU by “importing” the voltage control circuit.
In our opinion, due to the 22nm manufacturing technology, the developers decided to lubricate again between the cap and the CPU core and not solder. For the time being, we can’t say whether, like the Ivy Bridge processors, a lower quality thermal conductor was used here, this will be visible when it is replaced by more courageous testers. As a matter of fact, the built-in voltage regulator is again a component that makes cooling difficult, and there are visible signs of this.
HardOCP has released statistics for ASUS that were born after hundreds of Haswell overdrives. Based on these, we start with roughly this chance: two-thirds of the processors (exactly 70%) withstood the 4,5 GHz clock, and every third copy was stable at 4,6 GHz. Unfortunately, only one-fifth of the CPUs tested reached 4,7 GHz, and barely ten percent reached 4,8 GHz. So for a successful overdrive, a (good) dose of luck, a core voltage of roughly 1,275 volts and a great cooling system - like the Corsair H80i - will be essential again.
Even further time in this area. It is interesting for the new generation that we can now increase the 100 MHz BCLK value to 125, 167 and 250 MHz, but unfortunately only for the K, ie models with an open multiplier lock - King Matthias and the story of the wise girl in a modern edition.
Many fans are not happy with the progress the Core i7 4770K has made. Intel had previously seen an improvement of 5-15%, which is no longer very significant in itself, but the first experiences took the bench a little further down. THE Pro hardware its overall results show a barely 5 percent improvement, although subtracting Apache’s remarkably poor results, it jumps to 8,4 percent. That’s all we have to do now, anyway, it would be foolish to call the newcomer weak.
It is definitely worth mentioning the changes to the IGP. Right here is the Iris Pro 5200, which has been given a kind of fourth-level cache (eDRAM), making it occasionally accessible to the GeForce GT 640 and GT 650M, if not on average. Intel's solution, on the other hand, results in much smaller size and power consumption, so the Intel Core i7 4770R, which uses a BGA enclosure on the Iris Pro IGP desktop, should be discarded. Of course, the much more modestly resource-intensive Intel HD 4600 (found in high-end desktop CPUs) is making significantly less progress, with a 25-30% jump from its predecessor.
Smaller Haswell models (Core i 3, Pentium, Celeron) are expected to appear later.
