Intel Core i7-2600K vs Intel Xeon E3-1270

A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit applications.

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

Best

A higher transistor count generally indicates a newer, more powerful processor.

Best

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.

Best

With integrated graphics you don’t need to buy a separate graphics card.

Best

A larger L1 cache results in faster CPU and system-wide performance.

Best

More data can be stored in the L2 cache for access by each core of the CPU.

Best

More threads result in faster performance and better multitasking.

Best

A larger L2 cache results in faster CPU and system-wide performance.

Best

A larger L3 cache results in faster CPU and system-wide performance.

Best

This is the maximum rate that data can be read from or stored into memory.

Best

It can support faster memory, which will give quicker system performance.

Best

More memory channels increases the speed of data transfer between the memory and the CPU.

Best

The maximum amount of memory (RAM) supported.

Best

The bus is responsible for transferring data between different components of a computer or device.

Best

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.

Dynamic frequency scaling is a technology that allows the processor to conserve power and reduce noise when it is under a light load.

AES is used to speed up encryption and decryption.

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.

It is easier to obtain better performance when using virtualization if it is hardware-assisted.

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.

Best

NX bit helps protect the computer from malicious attacks.

This benchmark measures the performance of the CPU using multiple threads.

Best

This benchmark measures the performance of the CPU using a single thread.
