I've been working on hardware for over a decade, from the two-way server in the early years to the various controls that followed, and the parameters of the e5 series of cpus are almost sophisticated. The range ranges from e5-1600 to e5-2600 v2/v3/v4, with core numbers ranging from 4 to 28, and tdp from 60 w to 145 w. Many of the friends who assembled the second-hand server had a misty look at the model numbers, and today these key parameters are made clear。
How about the e5 parameters? Look
For the most common e5-2680 v3, 14 nuclear 28-wire 2. 5 ghz, wisdom 3. 3 ghz, l3 cache 35. 5 mb, tdp 120w, supports the rdr 4-2400 four-way memory. See also e5-2670 v3, 12 nuclear 24-range, main frequency 2. 3ghz, tdp, same 120w, and ddr4-2400 four-way. The "v" in the model represents version generation, v3 is the broadwell structure, v4 is changed to haswell-ep, with the main frequency and cache adjusted. Look at the three cores of the parameters:Core threads, tdp power, memory support specificationsAnd these three are direct decisions about how you can fit into the main board, how many memory strips you can plug in, how much of the cabinet you can handle。
Old models such as e5-2650 v2, 12 nuclear 24-range but with a main frequency of 2. 6 ghz, tpp 115w, walk through the ddr3-1866 four corridors. If you have the x99 main panel, both v2 and v3 can be plugged in, but different rams directly affect the actual bandwidth. The most specious way to check the parameters is to go to the intel ark official network input model, pull all specifications out of comparison, which is much more spectatic than the electricity provider's detailed pages, which often omit key items。
Comparison of e5 series cpu parameters
E5-2680 v4 (14 n28, 2. 4. 3. 3 ghz, ddr4-2400, 85 w) and e5-2696 v4 (18 n36, 2. 2/3. 6 ghz, ddr4-2400, 135 w) are the two most prominent for value. The generation of v4 has crushed the tppFull capacity varianceIt's very clear that the heat-dispersion pressure in the small room is very small. The early v2 series is now more expensive because of the basic cut-off in the ddr3 memory, which does not recommend new machines。
In terms of mononuclear performance, the e5 series, after all, does not follow game frames, and the e5-2699 v4 single nucleus runs are similar to i5-9400. A load such as multiple containers, large-scale projects, database clusters and so on is a multi-nucleus, with more than 24 nuclear models leading the experience fault。
Selecting the e5 parameter does not focus solely on the core number. The three hard constraints, the main panel slot, the memory channel number and the tpp cap, are identified first, and the rest is to select the most appropriate number in the budget。
