I was of the opinion that Intel will only face real competition when arm reaches parity with desktop class cpu. Nice to see AMD rise back up again. Hope Intel is not able to strong arm the oems like last time when AMD had design wins but Intel using anti competitive practice stalled its growth till it was able to catch-up and later go ahead.

I doubt we'll be seeing desktop ARM systems any time soon, especially high end workstation or enthusiast systems. The problem is that the ARM64 architecture is completely different from x86-64, which almost every desktop application is compiled for exclusively . Remember when Microsoft launched an ARM Surface? It had a special version of Windows, and almost nothing would run on it, as very few applications are compil…

What made the RISC or ARM processor popular in the past was the ability to do graphic rendering and complex math. GPU's put a dent in that. Making a i386 CISC system with the addition of a GPU have parity with the old SG systems, but substantially cheaper.

Does any remember the DEC Alpha? Windows NT 4.0 was ported to it. The Alpha was a 64-bit RISC processor. (Reduced Instruction Set Computer) An ARM is just an Advanced RISC Machine. RISC architecture has an instruction execution advantage over CISC (Complex Instruction Set Computer) that is what Intel is famous for. Although they did have a i860 and i960 RISC which many of them were for embedded military systems. Othe…

Yes, I actually managed a SQLServer computer running on a DEC Alpha machine. I don't remember anything specifically wonderful about the DEC other than it was one of the biggest servers I had seen at the time and it had a large ducted fan in the front for cooling. Neato!

What makefile/build system r u using ? I am curious since i did some work on parallel builds and I always wonder how much of this is (easily) transferable to other setups...

A modified version of the standard FreeBSD build, with bsd make. Eg, a script driven 'make -j X buildworld && make -j X buildkernel'

if you had access to a hosted build system, which is x10 faster. lets even assume some sort of transparent gradual sync of your source tree, and the binaries back to your system.

would u find value in such a setup or is it not worth the hassle ?

(lets assume the output is veritably binary-identical to your local build)

That sounds frivolous versus a single high-end PCIe SSD. Wouldn't be surprised if the improvement in real-world game load times wasn't even perceptible.

>That sounds frivolous Maybe, but that's what being an enthusiast is all about :) also assets (models & textures) need to be loaded from disk during game-play which can result in stutter when gaming. Faster IO would help here.

Our baseline of a single high-end PCIe SSD isn't slow, though. This comparison is ultra high bandwidth vs ultra ultra high bandwidth.
