I checked the link you shared. It appears to point to a product page for a coprocessor from HP, not an Intel one. The description mentions it's part of HP ProLiant servers, so it likely serves as an accessory or component for those systems.
For tasks needing special handling, if you're unsure of its purpose, it's usually unnecessary to use it.
It functions as an x86 CPU housed in a PCIe expansion card. This unique piece of hardware is highly specialized, with few programs capable of taking full advantage of it. Xeon Phi has been phased out this year, indicating it's no longer in active use. https://en.wikipedia.org/wiki/Xeon_Phi
The Xeon Phi is a manycore processor designed for MIMD tasks. Unlike GPUs that handle SIMD operations (such as processing entire vectors at once) and CPUs that work with SISD instructions (basic single-operation per data), the Xeon Phi excels at executing a single operation on one piece of data. Compared to a standard i7 CPU, it’s more similar to a basic atom core, but packed with many cores. This makes it suitable for applications that can simplify complex work into straightforward tasks. Some run smoothly on Windows or Linux because they use x86 architecture, though performance remains poor and benefits are limited—custom programs or frameworks like OpenCL may offer better results.
The chips in those devices feature weak general x86 processors combined with powerful FP64 FPUs. They occupy a middle ground between CPU and GPU ideas. Cores lean more toward CPU characteristics but are scaled more like GPUs. FP64 performance has been declining in consumer hardware. After the Nvidia 500 and AMD 200 series, modern GPUs have seen significant efficiency drops in this area. Some high-end GPUs still offer solid FP64 speeds, but at a premium cost. The Radeon VII stands out as a recent exception—it was essentially a rebranded pro-grade card, retaining good FP64 performance for its price, and remains sought after by enthusiasts. On the CPU side, Intel is advancing with AVX-512, delivering roughly double the speed of standard cores. AMD lacks a direct match, remaining only slightly ahead of regular Intel cores but compensating with higher core counts.
It's not just similar to a weak atomic core—it's actually quite poor. It exists mainly to support the CPU operation. The intensive tasks are handled by the powerful FPU, which manages floating-point calculations. Think of it like a drag racing car: the core provides enough strength to keep everything moving. If you're focusing heavily on the core components, you're missing the point.
If you need multiple old rigs handling one job in a cluster, this setup can achieve it without needing extra shelving space. It’s similar to linking several Raspberry Pi devices, but the processor type is x86 instead of ARM and performs much better for professional versus casual use. You could fit eight of these units in a single case, giving you 8 times 72 cores, which was also feasible back when a 28-core chip cost less than a new economy car. This setup isn’t really suited for everyday consumer tasks—perhaps it’s more for running many older game servers or niche applications.
This Intel Atom is the processor. My HP laptop used an Intel Atom, and the Xeon Phi contains several of them. Intel made a variation for HT, changing the setup. Typically it has one core with two threads, but here it's one core with four threads. Therefore, a 64-core Xeon Phi can generate 256 threads.
