Processors

The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in use in the computer industry at least since the early 1960s. The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.

CPU socket
i

CPU socket

A CPU socket or CPU slot is a mechanical component that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the CPU to be replaced without soldering.
Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with a large number of pins, either zero-insertion force (ZIF) sockets or land grid array (LGA) sockets are used instead. These designs apply a compression force once either a handle (for ZIF type) or a surface plate (LGA type) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket.

64-bit architecture

In computer architecture, 64-bit integers, memory addresses, or other data units are those that are at most 64 bits (8 octets) wide. Also, 64-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.
The Basic advantage of a 64-bit System is, that more than 4GB RAM can be adressed.

Number of processor cores

A multi-core processor (or chip-level multiprocessor, CMP) combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (IC), called a die, or more dies packaged together. A dual-core processor contains two cores, and a quad-core processor contains four cores.

Max. TDP
i

Max. TDP

The thermal design power (TDP), sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat without exceeding the maximum junction temperature for the computer chip. It can do this using an active cooling method such as a fan or any of the three passive cooling methods, convection, thermal radiation or conduction. Typically, a combination of methods is used. The TDP is typically not the most power the chip could ever draw, such as by a power virus, but rather the maximum power that it would draw when running "real applications". This ensures the computer will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power (which would cost more but in favor of extra headroom for processing power).

L1 Cache
i

L1 Cache

A CPU cache is a cache used by the central processing unit of a computer to reduce the average time to access memory. The cache is a smaller, faster memory which stores copies of the data from the most frequently used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.

When the processor needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, the processor immediately reads from or writes to the cache, which is much faster than reading from or writing to main memory.

Most modern desktop and server CPUs have at least three independent caches: an instruction cache to speed up executable instruction fetch, a data cache to speed up data fetch and store, and a translation lookaside buffer (TLB) used to speed up virtual-to-physical address translation for both executable instructions and data. Data cache is usually organized as a hierarchy of more cache levels (L1, L2, etc.; see Multi-level caches).

L3 Cache

L3 Cache

Another issue is the fundamental tradeoff between cache latency and hit rate. Larger caches have better hit rates but longer latency. To address this tradeoff, many computers use multiple levels of cache, with small fast caches backed up by larger slower caches.

Multi-level caches generally operate by checking the smallest Level 1 (L1) cache first; if it hits, the processor proceeds at high speed. If the smaller cache misses, the next larger cache (L2) is checked, and so on, before external memory is checked.

As the latency difference between main memory and the fastest cache has become larger, some processors have begun to utilize as many as three levels of on-chip cache.

Transfer rate

Transfer or the more common derivatives Gigatransfer (GT) and Megatransfer (MT) are terms used in computer technology, referring to a number of data transfers (or operations). They are most commonly used for measuring transfer rates (usually as transfers per second, GT/s, MT/s, etc.). 1 GT/s means 109 or one (US/short scale) billion transfers per second, while 1 MT/s is 106 or one million transfers per second.

SSE4

SSE4

SSE4 (Streaming SIMD Extension 4) is a CPU instruction set used in the AMD K10 (K8L) and Intel Core microarchitecture.ntel SSE4 consists of 54 instructions. A subset consisting of 47 instructions, referred to as SSE4.1 in some Intel documentation, is available in Penryn. Additionally, SSE4.2, a second subset consisting of the 7 remaining instructions, is first available in Nehalem-based Core i7. Intel credits feedback from developers as playing an important role in the development of the instruction set.

AMD currently supports only 4 instructions from the SSE4 instruction set, but have also added four new SSE instructions, naming the group SSE4a. These instructions are not found in Intel's processors supporting SSE4.1 and alternatively AMD processors aren't supporting Intel's SSE4.1. Support was added for SSE4a for unaligned SSE load-operation instructions (which formerly required 16-byte alignment).

AVX

Advanced Vector Extensions (AVX) is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008.
AVX provides new features, new instructions and a new coding scheme.
The width of the SIMD register file is increased from 128 bits to 256 bits, and renamed from XMM0–XMM15 to YMM0–YMM15. In processors with AVX support, the legacy SSE instructions (which previously operated on 128-bit XMM registers) now operate on the lower 128 bits of the YMM registers.

The Haswell-R sweet spot

IMHO, the 1231 has been Intel's best CPU in this price range since its launch, unless of course you need the iGPU. Then, obviously, the 1231 is a not an option, and you might want to look at the i7 (K-series especially) as prices converge very quickly after the 300.- mark.

Here's a brief description of my use case:
- Personal workstation
- OS is Debian Jessie
- Main use is web development and constantly building and provisioning both server and desktop VMs.

The box with the 1231 at its core performs admirably. The cooling is all stock, but the temps stay very close to idle, even when cores are active during builds or similar. No problems with GNU/Linux whatsoever. The system's 100% stable, even though the RAM is non-ECC (no time to find anything from ASRock's QVL, sorry).

The last point I really want to stress and really the major reason why I picked this particular CPU to build my system around is the quad core and HT support, since I really need this, and I need to work it smoothly. Which, amazingly, is exactly what you get for 263.-! The price for a 4/8 configuration, on a pretty fast (3.40/3.80 eats tasks, it's beautiful)., is unbelievable to me.

In conclusion, I feel that the E3-1231v3 is a really good deal: you can't get a cheaper multi-threaded quad-core, and, aside from the iGPU, it performs as well as the similarly-clocked i7s.
