"On July 18, China Environmental Protection Department submitted documents to the World Trade Organization (WTO), requiring urgent adjustment of the list of imported solid waste, which is intended to import 4 categories of 24 solid waste before the end of 2017, including life sources waste plastic, vanadium Highly polluted solid waste such as unscated waste paper and waste textile raw materials.
In the summer of 2017, China-US trade disputes had a new situation. On July 18, a paper ban made many people aware of the harm of "foreign garbage". The ban did not emphasize electronic products directly, but the "foreign garbage" of electronic products is actually a class of relatively largest exposure. Our "foreign garbage" today is the Xeon E5 series CPU, which belongs to the broad garbage category, but it is relatively close to the "antique gold" concept of electronic products.
Xeon Strong is a processor series of Intel, born since 1998, INTEL aims to distinguish between server markets and personal PC market innovation initiatives. In the past 19 years, Xeon has a leafy leaf, endless, the recent number of family models far exceeds the same period desktop, notebook platform, let anyone who wants to combat his development history but step.
The quantity cannot explain all problems, but it is possible to confirm the influence and vitality of the Xeon brand in the corresponding market, from the side to confirm the technical strength of Intel. In recent years, Although Intel's development strategy has been moving the rear desktop, the importance of the Xeon family has been arranged before the desktop personal user CPU, and can even say that the latter is completely the former's castration set.
Specifically to our well-known product line, E5 12XX series SLR to strong correspondence desktop i5 / i7 four core LGA 115x platform concept has been deeply rooted. Prior to 2017 River Successfully Leads the desktop multi-core wave, the popularity of civil multi-threading has always been the "God of War", "God Education".
Of course, at this moment, it is the tying time of Ryzen 7, Threadripper, Core I9 and other multi-core monsters, E3 has become a cost-effective toy toy, away from the center of public opinion. Our important discussion today is the market situation of the E5 1500/2600/4600 series of Xeon processors in the market.
Since these processors have the number of core numbers of the CPU in the long-term desktop platform, there are many unknown channels, the second-hand circulation, and the Nostalgic Party represented by Tu Latin, and the mass needs should be dealt. The middle user of the super multi-threaded task needs, and it has been self-cultivating the "garbage" of the "foreign garbage".
E5 foreign garbage: "Who are we?"
Xeon's latest generation SKYLAKE-SP / W has changed naming way, becoming new "gold and silver copper platinum combination", so the effort to the Core I7 / I9 7000 series will be changed to change, no longer call E5 . Then the E5 series CPU currently four generations have become an unprecedented loneliness series.
From the perspective of longitudinal direction, the four generations E5 can be divided below:
One: Sandybridge -EP family, corresponding to I7 2600K and other second-generation Core architecture, publish release with I7 3960X (Sandybridge -e) approximate time period, product naming has no embedding, corresponding to x79 motherboard chip group LGA 2011 platform.
IVYBRIDGE -EP family, corresponding to the three generations of Core architectures such as I7 3770K, released from approximate time periods such as I7 4960X (Ivy Bridge-E), product suffix V2, corresponding to X79 motherboard chipset LGA 2011 platform.
Three: Haswell-EP family, corresponding to the four generations of four generations of Core architecture such as I7 4770K, released from approximate time periods such as I7 5960X (Hawell-e), product suffix V3, corresponding to X99 motherboard chip group LGA 2011-V3 platform.
4: Broadwell-EP family, corresponding to the five-generation Core architecture such as I7 5775c, released from approximate time periods such as I7 6950X (Broadwell-e), product suffix V3, corresponding to X99 motherboard chipset LGA 2011-V3 platform.
Switch to the horizontal, each generation of E5 series will have 1600/2600/4600 three series
E5 1600 series
Usually the vest series of the desktop I7 HDET platform, in V1, V2, V3 can overclock, V4 is locked, the multiplier _ such as E5 corresponds to I7 5960X. This series generally has some frequency, HT, etc., which is more frequent, and HT, etc. in full correspondence. All E5 series support ECC memory, which only supports single CPUs.
E5 2600 series
E5 main series, from dual-core to twenty-two cores, from 2.0GHz to 5.1GHz (NASA customization) distribution. At present, the main circulation is the model of more than 8 cores of E5 V3 / V4. E5 2600 Series will have two high-frequency version of the full load frequency of more than 3GHz. The core quantity is in the same medium. The most recent representative is E5 2687W V3 and E5 2689 V4.2600 is a double series, original and desktop I7 is not very pair. But E5 2689 v4 can basically see the dual-channel specification version of the desktop I7 6950X.
The E5 4600 series is a four-way platform. It usually does not as possible than 2600 series, often there will be some strange strange specifications, such as 6C6T without hyperthreading. However, the four platforms have a huge memory bandwidth, which has unique advantages in some areas.
The official model of the entire E5 family is very large. If there are various ESs that are not obvious, it is like a river, and even the vest army of the notebook camp will be worse. So multi-models will not flow into the "foreign garbage" market of Taobao and physical stores, and many of the price is no market, and the supply is not stable.
In general, there will always have a lot of explosive products in the same period, most is a low frequency super multi-core, a small number is a model with a high medium number of cores, and the situation in the foreign garbage market will analyze in the last page.
E5 foreign garbage: "Our users are?"
E5 series processors typically have the following features compared to desktop i7 series fever CPUs:
One: The frequency of the core is not high, one multiplier is not a password.
Second: There is a high frequency of individual models, either buy, or very expensive.
Three: You can double, but you need a non-cheap C600 series chipset, and ECC memory cost is slightly high.
Four: Theoretically, E5 does not have any special additions, can be combined with I7 to deliver single core and multi-core comprehensive performance through specifications. E5's strength is I / O performance, it is important to the server, and it is not important for the consumer market.
Therefore, we can thus infer the main user group characteristics of E5 "foreign garbage" circulating (not enterprise users) on Taobao private market. Users who really don't have money is all big customers. They go directly to buy the whole machine, or the company reimburses or yourself is the boss. If you want to rely on Taobao Tao's "garbage" to achieve multi-threadability, such users can be divided into the following categories:
One: E5 is a server processor, naturally can be used to build a small server, but a slightly large-scale website can go to the cloud server, and this application of E5 foreign garbage may limit the Internet cafes and personal website.
Its 2: E5 is often used in the commercial desktop machine to form a graphics workstation or video clip machine. Relevant practitioners do not take back the big tree, but also require strong multi-core performance, only from cheap Taobao channels. This requirement may come from scattered individual 2D \ 3D designers, graphic renderers, video workers, or small studios, may also come from school, structure, use the public.
Its three: E5 itself or high frequency or multi-core feature itself is designed according to some research computing projects. The strongest CPU - xeon E5-2602 V4 clock-threaded CPU - Xeon E5-2602 V4 is 5.1GHz, and the rumor is NASA custom use to calculate the atmospheric environment. In this research and professional computing market, although large companies and customers are subject, the practical demand for practitioners may not be able to meet their own machines through enterprise resource allocation, often need to customize their own machines to meet the needs. The author's Harkeeper friends bought multiple Ryzen 7 and E5 processors to conduct research projects.
Finally: Tucac, the graphics card "Base" (album claimed) DIY fever, the DIY fever, also interested in E5 to strong. From the LGA771 era, Xeon became a lot of "Panjiayuan Distribution Market" pursuing multithreaded users. The E5 of the same era has I7 unacceptable advantages in many ways, and some of the products of some players love.
E5 foreign garbage: "What kind of future is we?"
At present, the Xeon Skylake SP / W series has announced no longer supporting the X299 motherboard, and has been renamed, so the possibility of equipped the E5 processor with the civilian motherboard to obtain affordable possibilities. Fundamentally, future new to strong can become foreign garbage to see their own channel prices and motherboard prices for two years, too far without judgment. We only talk about the current E5 series and the corresponding motherboard.
Domestic Taobao and physical stores circulating the E5 Xeon series processors are sought after, in addition to satisfying some people's rigid demand, it is mainly cheaper. The reason why foreign garbage is called "garbage", or the top cover punch, or it is a re-lettering of the scratch (without excluding the possibility of stealing the column), or the engineering sample is a special channel. , Can use but there is no legal identity, and there is no risk.
Therefore, once the price is affected, the "foreign garbage e5" of the nearby position segment will be very embarrassed. At present, the low frequency within the Eight-core (2.8GHz) E5 2600 Series and E5 1600 Series have been strongly impacted by the AMD Ryzen series, and competitiveness is no longer.
The frequency of R5 1600X \ R7 1700 exceeds most six to eight-core E5 foreign garbage series processor, the B350 motherboard is also more cheap than X99, and the new product energy consumption is high and has a complete warranty. The comprehensive advantage is to rush. Garbage . Low-end products such as E5 2620 will gradually become true "garbage" and no one is concerned. Then the E5 2673 V3, E5 2683 V3 is cheaper CPU (within two thousand five), especially if the ES is developing?
For video users who need to use H265 latest decoders, this type of multi-core medium frequency star E5 products still have a strong advantage, and the Intel processor's AVX 2.0 efficiency is far non-Ryzen comparable. Intel's upcoming I7 8700K and other desktop Coffee Lake processors have only six cores. Only I7 7820X's cost-effectiveness is still possible in the X299 platform, but they absolutely prices are high, leaving this foreign garbage It's a relatively high space.
Compared with E5 2673 V3, E5 2683 V3 positioning higher level E5 2696 V3, E5 2686 V4 (ES) and other super multi-core medium frequency processors, pricing and eight-core Intel / AMD high-end processor almost (i9 7820x, Threadripper 1900X ). Their single-threaded performance is much different than the consumer-class processor, which will lose some scientific operation users and 2D images that require high frequency, but the main video and graphic rendering groups are still strong. In particular, the E5 2600 series can be dual, and the multi-threadability is achieved in a non-expensive motherboard, which is not until the consumer processor is far.
Really suffering will have a good look, a perfect balance between E5 3 / V4 processors, such as E5 2666 V3 / V4, E5 2687W V4, E5 2676 V4, they are The full load of 3.0GHz has too much difference between the I9 7900/7800 series or the Threadripper 1900 series, and the multi-thread advantage is not even less than the consumer level I / A processor.
These originally priced E5 "" foreign garbage "will gradually have a lot of people, take a long time to remember their market capacity. The more special E5 2689 V4 frequency is 3.7GHz, which is equivalent to the E5 version of I7 6950X, and the latter The current circulation price has been low to 7,000 yuan, and these two processors will be quite embarrassed.
In the market of more than 10,000 yuan, E5 2679 V4 up to 20 core 3.2GHz's comprehensive performance is only more than E5 2699A V4. In terms of cost performance, E5 2679 V4 is cheap and very prominent than I7 6950X. The strongest I9 7980XE that has not yet been released is only 18 core 3.4GHz full load frequencies, and its Xeon Gold 6150 is not capable of defeating 22 core 2.9GHz E5 2696 V4 in the evaluation. The price is much weaker than E5 2679 V4, impact Limited.
However, other frequencies of other frequencies in the Wanyuan market, if the cost is far less than E5 2679 V4, such as 14 core E5 2690 V4 products, will face Intel Core I9 7960X, AMD Threadripper 1950X Waiting for the double pinch, they have no ability to compete.
Therefore, finally, the X99 and C612 motherboards are getting cheaper, and the current cost-effective E5 2683 V3 and other multi-core real E5 survival space will not be too big; the original sword is tied to the front, the high frequency, E5 series of foreign garbage, which is unoulevful, etc., the E5 series of foreign garbage will fall, and it is severely blown.
Finally, it is necessary to remind consumers. Whether it is a six-core Core i7, I9, Xeon is still AMD's Threadripper, their second-hand market capacity is very limited. Compared with the long-term stable quad-core I7 of second-hand price, hold users who hold super multi-core CPUs. If the purchase price exceeds more than 4,000 yuan, it is inevitable to be a big bleeding when shooting.
The current market, multi-core optimization environment is not friendly, super multi-core processor's one, second-hand market relationship Similar to the "diamond" in the jewelry industry - the price of merchants is much higher than its repurchase price, passerby recognition The degree is extremely low.
