Intel Xeon E5-2640

16 Reasons why Intel Xeon E5-2640 is better

than the average

1.Plenty faster CPU clock speed
6 x 2.5GHzvs 4.7 x 2.3GHz (the average)
vs 8 x 8GHz (best: AMD Opteron 6220)
2.Clearly more CPU threads
12vs 7 (the average)
vs 48 (best: Intel Xeon E7-8890 v4)
More threads result in faster performance and better multitasking.
3.Noticeably higher PassMark result
10001vs 5515 (the average)
vs 17470 (best: Qualcomm Snapdragon 805 APQ8084)
This benchmark measures the performance of the CPU using multiple threads.
4.Measurably more memory bandwidth
42.6GB/svs 30.7GB/s (the average)
vs 192.2GB/s (best: Intel Xeon E5504)
This is the maximum rate that data can be read from or stored into memory.
5.Uses hyperthreading technology
Yesvs No (59% don't have it)
Many of Intel's processors use hyperthreading, which means that each core of the processor can work on two threads at once instead of most processors which work on a single thread per core. This means you can have significant performance gains in certain applications.
6.Noticeably more transistors
2270 millionvs 1458 million (the average)
vs 7100 million (best: Nvidia Tegra K1 (64-bit))
A higher transistor count generally indicates a newer, more powerful processor.
7.Distinctly bigger L3 cache
15MBvs 10MB (the average)
vs 60MB (best: Intel Xeon E7-8890 v4)
A larger L3 cache results in faster CPU and system-wide performance.
8.Significantly more memory channels
4vs 2 (the average)
vs 4 (best: Intel Core i7-3960X)
More memory channels increases the speed of data transfer between the memory and the CPU.
9.Clearly more L3 cache per core
2.5MB/corevs 1.8MB/core (the average)
vs 15MB/core (best: Intel Xeon E7-8893 v4)
More data can be stored in the L3 cache for access by each core of the CPU.
10.Slightly higher PassMark result (single)
1460vs 1444 (the average)
vs 2546 (best: Intel Core i7-4790K)
This benchmark measures the performance of the CPU using a single thread.
11.Appreciably newer version of PCI Express (PCIe)
3vs 3 (the average)
vs 3 (best: Intel Core i7-4770K)
PCI Express (PCIe) is a high speed expansion card standard, that connects the computer to it's peripherals. Newer versions can support more bandwidth and deliver better performance.
12.Supports ECC memory
Yesvs No (74% don't have it)
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
13.Appreciably faster bus transfer rate
7.2GT/svs 5.7GT/s (the average)
vs 9.6GT/s (best: Intel Xeon E7-8890 v4)
The bus is responsible for transferring data between different components of a computer or device.
14.A little bit higher clock multiplier
25vs 24 (the average)
vs 47 (best: Intel Core i7-4870HQ)
The clock multiplier controls the speed of the CPU.
15.Substantially larger maximum memory size
750GBvs 331GB (the average)
vs 4096GB (best: Intel Xeon E7-8870)
The maximum amount of memory (RAM) supported.
16.Somewhat higher SSE version
4.2vs 4.1 (the average)
vs 4.2 (best: Intel Core i7-4770K)
SSE is used to speed up multimedia tasks such as editing an image or adjusting audio volume. Each new version contains new instructions and improvements.
