Ok, ima smisla manje više, ali nije baš da AMD i Intel moraju da razvijaju 15 različitih čipova za sve segmente. Svi su manje više isti, segmentacija je namerna. Što je zapravo dobro, jer za razliku od Apple-a, ipak imaš i modele od 300-500€. Koliko sam pratio, u segmentu od 700-2000€ idu ili 6-core ili 8-core modeli (ima i 4-core izuzetaka, ali kome to treba :d). Tako da zapravo i intel pravi jedan procesor koji ide u sve NUC/miniPC, laptop i AiO uređaje, baš kao i Apple. Samo što Intel korisnici ipak imaju veći izbor
Mislis veci izbor da budu izbuseni?
Mi godinama placali HEDT procesore koji mogu da teraju ECC (memorijski kontroler unutra ima ECC - bukvalno nema sta da se PIPA i radice), mogu cak i 2S da rade (sve unutra - QPI/UPI linkovi su tu, itd.).
Ali ne - hoces taj segment? Moramo da kupimo Xeon, ne moze bre ECC ili 2S/4S sa HEDT... ok kupimo Xeon, ali onda nema OC, nema visoke frekvencije (osim ako ne platis ohohoooo)... zasto?
Segment :-)
Onda je Intel krenuo da se 'urci - ajmo K verzije desktop nemaju vPro, neko vreme nisu imali ni VT-d... sto?
Segment :-)
Oces te "poslovne" stvari? Moze, ali onda nema K (tj. ima K, ali neka druga rec). Sto?
Segment :-)
Uprkos problemima u R&D-u Bob Swan je imao tim ubica za segmentaciju - Skylake SP je postao horor.

The Platinum Skylake chips offer the fastest 2.67 GHz DDR4 memory, capacities up to 1.5 TB per socket, full AVX-512 floating point, and up to three UPI links for scalability from two to eight sockets. If you just want to build a two-socket server with maybe 512 GB of memory, you are paying a lot of AVX-512 and NUMA tax if you want high core counts with modest speeds or high clock frequencies with four cores compared to the prior Xeon lines. This will be a conundrum for many customers. And this is definitely the behavior of an IT vendor at its peak. Whether this is a local maximum for the Xeons or the last Xeon peak, we shall see.
Ovo je 2017 btw.
A sto?
SEGMENT :-)
Ali avaj - to je istih 50% koji su morali da bace kad se pojavio EPYC2. I tek ce da se cesu sa ARM-om.
Poslednja kap je bio novi uCode update za neke desktop procesore, kako bezobraznici slucajno ne bi mogli da OC-uju na plocama koje nisu autorizovane + ona beda gde ogranicavaju DDR4 brzinu po cipsetu (koji NEMA NIKAKVE VEZE SA BRZINOM MEMORIJE). Ali tad je vec stvar bila gotova, AMD je bar bio tu.
I tako treba da bude, za korisnike. To perverzno segmentiranje je samo bio znak totalnog monopola. Bas kao pomenuta auto industrija - mnoogo bilo lepo kada si jedini baja i kad se zna kako ide nomenklatura i koliko treba da se plati za skok.

Citat:
You might recall with Skylake era Xeons, Intel introduced the reviled crippled memory SKUs with the -M prefix. This meant if you needed more than 1.5TB of memory per socket, you had to pay a >$3000 tax per socket for Intel not to blow a fuse on your CPU. This obviously went over like a lead balloon with customers but the idea was to juice sales for the moribund Optane DIMMs which no one other than one customer SemiAccurate can find actually wanted. The kicker to all of this was that Intel took the pain of the blatant gouging but didn’t actually launch the DIMMs that took advantage of it until Cascade Lake launched. In the history of own goals, this one is right up there.
Then we get to Cascade Lake, a bug fixed Skylake CPU that came out about two years later. This time there were two ‘large memory’ SKUs, the first being -M for those who need >1TB of memory that the non-suffixed Xeons support but <2TB that the -Ms max at. This adds a mere $3003 to a base Xeon. The -L up the limit to 4.5TB, effectively the max possible with a 256GB DRAM and a 512GB Optane DIMM. For the privilege of not blowing two fuses, Intel charged customers a mere $7897, it takes a lot of work to not blow those two fuses AND add a -L to the etchings on the heat spreader you know.
