发帖数: 68029 | 6 Intel Releases Core i7-2700K and Cuts the Prices of Three CPUs
Intel has quietly released a new top-of-the-line Sandy Bridge CPU: Core i7-
2700K. We reported the i7-2700K "leak" about a month ago, and guessed that
i7-2700K will be released around the same time as AMD's Bulldozer CPUs,
which ended being quite accurate. In terms of specs, 2700K is very similar
to 2600K - the only difference is the extra CPU multiplier and hence the
extra 100MHz in 2700K. That means 2700K has default frequency of 3... 阅读全帖 |

Core i5 and i7 CPUs to be overclocked by up to 400MHz using Turbo
multipliers. Reaching for higher speeds required pricier K-series chips, but
everyone got access to a little "free" clock headroom. Haswell isn't quite
so accommodating. Intel has disabled limited multiplier control for non-K
CPUs, effectively limiting overclocking to the Core i7-4770K and i5-4670K.
Those chips cost $20-30 more than their standard counterpart... 阅读全帖 |

Modern motherboards don't have "integrated" graphics, per se. The current
paradigm is that some CPUs have graphics processing units (GPUs) built into
the CPU (AMD calls these APUs, rather than CPUs). In order to utilize this
built in GPU, you need a motherboard that has the necessary circuitry and
connectors to enable the GPU to connect to a display.
In this case, this motherboard does have this circuitry, but you must
install an APU in order to use it. The new Ryzen CPUs that just came on the... 阅读全帖 |

Faint, don't make such comments on sth you don't know.
2 CPUs have communication overheads, 4 CPUs will only have more.
The advantage of more CPUs is:
If you code can be well parallized, it's much faster, many simulation code
can be 2 times faster on a 2 CPU machine, what's really difficult is to
achieve scalability on very large machines.
Even if you only run it on one CPU, you can run two jobs at the same time.
So if you have computational considerations, 2 CPU is definitely worth it. |
