AMD overclocking world record with a CPU pre-series sample

AMD overclocking world record with a CPU pre-series sample 

Overclocking with helium cooling: After several days of preparations for the successful record attempt. 
AMD Though you can buy the AMD FX aka Zambezi with the new bulldozer microarchitecture nowhere, but the overclocker "Team AMD FX" has a pre-series sample already driven into the Guinness Book of Records: For cooling with liquid helium reached the processor at 31 . August 8.429 GHz. He outdid the first 12 days previously reached the maximum value of 8.309 GHz to 1.4 percent. 

Were at a record-clock frequency according to the CPU-Z screenshot, which serves as a "photographic evidence", only two of the eight cores of the engineering sample (ES) of an FX-8150 is active. The entry to record the website reveals more details about the FX series, for example, holds that each of the dinuclear bulldozer modules 2 Mbytes L2 cache (16-way associative) and the FX-8150 and another 8 MB of L3 cache. Also, the AVX-orders are expected to be present, but also the XOP extensions. 

All FX processors, AMD should make it easier to overclock with unrestricted multipliers. Even with high-performance air coolers or water coolers are simple clock speeds of "well over 5 GHz," to be accessible, such as AMD-manager Simon Solotko in a blog post promises. He also belongs to the AMD FX team. 

The announcement of the record clock frequency of AMD is not by chance just today, but because Intel Erzkonkurrent in San Francisco his Intel Developer Forum (IDF) opened. Benchmark results published an FX AMD, however. Recently, AMD had confirmed the FX will launch in the fourth quarter - to speculate about a meeting in October. 

Because the bulldozers microarchitecture significantly from that of its predecessor and also K10 differs from that of Intel Core processors i, can the performance of the FX CPUs hardly estimate. With great anticipation, therefore, the idea of ​​the equipped with four to eight cores, or more bulldozers two to four modules FX series is for the AM3 socket + expected. Among other things, it is unclear whether similar to the FX software with real per clock cycle processed many orders as Sandy Bridge processors - it would be less, he would need higher frequencies in order to outdo the competition. Against this background, it is an interesting coincidence that the previous record was an elderly CPU Celeron D 352 with the discarded Intel NetBurst architecture: this was aimed at extreme frequencies. On the other hand, it has also managed IBM's about bringing the power of multiple processors as standard at frequencies greater than 5 GHz. 

About to start the anticipated FX versions there are only speculations. However, have since been spotted at an online shop selling some prices, there is the cost-FX-8150 with eight cores and 3.6 GHz clock speed nominal $ 266. Meanwhile, Intel plans to introduce a supposedly Core i7-2700K with unrestricted multiplier and also a clock frequency over the 3.4 GHz of the previous flagship LGA1155 Core i7-2600K. The latter currently stands at 317 U.S. dollars on the Intel price list.
