The new Apple processor is based on the ARM architecture instead of the X86 used by both AMD and Intel. And now we are going to go through the performance and price/performance competitive analysis that these two chip makers have done as they talk about their impending server chips. Xeon (x86) Cascade Lakes has been just good enough to keep business, data processing, production operations and communications up and running, this generation of infrastructure, on Intel’s ability to supply incumbent use concerned with keeping product market and financial share and business humming along. It is hard to say, but that gap could close up. The pricing on such a chip, we think, would be even more aggressive and go after the belly of the Xeon SP market: Those aptly named Gold processors, like the new Xeon SP 6238R. And you made that very same exact point in the paragraph preceding the sentence quoted above: > It’d be better if they just ran benchmarks with the same neutral non-cheating compilers with the same flags on both their chip and whichever competitors they are comparing with. wmf 1 hour ago. x86 is hamstrung to 4 because of legacy. Bet you get voted most edgy cool dood on earth! It goes down strongly as negotiating power of the customer increases (i.e. The workloads are just workloads, which may or may not be representative of workloads that customers actually care about. In how many ways can I select 13 cards from a standard deck of 52 cards so that 5 of those cards are of the same suit? It’s just convenient because with SPEC people know at least exactly what the version of exactly whicb application code is being run, since it doesn’t change. To me, it looks like that this is because x86 is a CISC architecture while ARM is a RISC architecture. Further, the SOC has unified RAM that offers ridiculously fast data transfer. That brings us to the last chart in the deck from Ampere Computing, which shows the performance per total cost of ownership deltas between the four chips shown below: This is a system level comparison and the rack of servers using the Altra processors are using a pair of those 180 watt parts (which we estimated some feeds and speeds for) plus sixteen 16 GB memory sticks (256 GB of memory), a pair of Ethernet NICs, a 1 TB SATA drive, and base components like baseboard management controllers, power supplies, and such. Comparison above excludes for no good reason (except if trying to “prove” something that isn’t true) AMD CPUs with best price performance ( 7352, 7402 and 7452 and 7702P ) any of which have price/performance better than Ampere Altra even when using rather strange metrics used. At this time beginning now and into the next 60 months, the total available market for processors of all types supporting existing infrastructure and build out exceed 1.5 trillion units of Xeon in use. This machine had a base SPEC integer rating of 342, which after a conversion to estimated GCC results by multiplying by 76 percent yields 260 and that works out to 130. But what the tests are really comparing? I thought I'd do a head-to-head comparison with some hardware I already have. Let’s start with Ampere Computing and how it thinks its first generation Altra chip will do against the competition in the datacenter, beginning with SPECrate 2017 Integer tests: The Ampere Altra chip tested is presumably the 80-core version; it’s not clear. Do studs in wooden buildings eventually get replaced as they lose their structural capacity? And while the Arm server chip upstarts, Ampere Computing and Marvell, were not planning for a global pandemic when they timed the launches of their chips on their roadmaps, they may be among the beneficiaries of the budget tightening that will no doubt start at most companies – if it hasn’t already. So loads of ongoing IP acquisition and bigger interests buying up smaller interests. The SPEC integer test for that machine, a Dell PowerEdge R6525, is here. Take a look at the whole market; client base station, cell network, network edge, metro edge, data center processing, aggregation, switch and route; public, private, enterprise, government communications, telecommunications, packet processing and inspection, security, switch and route, long haul carrier network and control; rural, suburban, urban spoke and hubs, network computing, HPC and supercomputing. The first thing that Marvell wants everyone to ponder is just how many virtual machines each one of its processors can host. Real question on my mind is when ARM reaches parity with x86 across the board are the higher end ARM chips going to be able to match something like the Intel i7 and AMD Ryzen 7 in performance per watt.
