Celeron M520 or Celeron 420 Which of the two CPUs is better, and what is the price?

The biggest difference is also that their cores are different, Celeron M520Merom cores and Celeron 420YONAH cores.

After all, the Merom kernel is ahead of the Yonah generation, and there are quite a few differences between them.

YONAH is the first generation of Core dual-core technology released by Intel, and MEROM is the latest Core 2 dual-core technology, although it is said that it is applied in Celeron processors, many new features of MEROM (such as front-end bus, L2 cache) can not play an advantage, and from the actual data, it is the same as YONAH's, but there are still many new MEROM performance is more prominent.

The addition of a dynamic execution channel, increased throughput of the SSE instruction set, increased functional memory access, advanced intelligent cache dynamic cache allocation, and lower power consumption all make Merom even more attractive.

After the price adjustment on July 22, the Celeron M520 has been reduced from the original $107 to the same $86 as the Celeron M440. I believe this is also the main reason why many notebook manufacturers have upgraded their Celeron M440 notebooks to Celeron M520!

Seyan M is for notebooks,Sejan 4 is a desktop processor,If you want to buy a desktop, it is recommended that you buy a dual-core one,AMD's game performance is stable,Core dual-core is better for office。

Celeron M is for notebooks.

The performance of the notebook is not good, few notebooks can fully exert the performance of the CPU, especially in games, because the graphics card of the notebook is not as good as the desktop, what does it have to do with the processor? Recognized to play games with a look at the graphics card! The above is the comment, let's get to the point:

In terms of performance, Celeron M530 is far stronger than Benrot only 4 Celeron because:

1, Celeron M530 is a core 2-core mobile processor, is a simplified version of the mobile Pentium T2000 series (mobile Ben7 processor) dual-core processor, its architecture, execution efficiency, are far stronger than Ben4, not to mention Celeron. Celeron M530 is a Blind Blind Lite Mobile Ben 7 processor (Celeron belongs to the Pentium series products). Ben 7 is definitely stronger than Ben 4.

2. The performance of the processor is determined by the architecture, main frequency, front-side bus, and L2 cache. Celeron M530 is the architecture of the Core 2, Celeron is the NB architecture of the Ben 4, and Celeron M530 is strong; Celeron M530 front-end bus is 533MHz, Celeron front-end bus is 400MHz, Celeron M530 strong; Celeron M530 L2 cache is 1024K, Celeron L2 cache is 128K, Celeron M530 strong;

3. And the thermal power consumption of mobile processors is very low, which is much more stable than desktop processors. If you compare the processor alone: the mobile Celeron M530 processor is much stronger than the desktop Celeron processor.

To add:The mobile Celeron processor of the notebook,The architecture grinds the hollow is the NB architecture of the mobile Ben4,The main frequency is,The front-side bus is400MHz,The L2 cache is256K,The performance is stronger than the desktop Celeron processor,But compared with the Celeron M530,It's still much worse。
