Almost nine years later, Mac Pro with Westmere Xeons still has decent scores. Hold better than I thought - but that is pure Intel fault.

MP5,1 is the modern SE/30.
Amazing isn’t it!

thats the reason all 3D rendering is heading towards being GPU powered, at least with GPU’s there still seems to be a decent speed bump with each new generation.

Or, is it Maxon's fault for still compiling their code for a nine-year old processor?

When code is recompiled to use the new instruction set extensions, it can be significantly faster.

Compiling for MMX and running on a system with AVX2 should be a crime. ;)

If AVX and AVX2 where so good and could be applicable to everything as Intel wanted to sell us, every Pro app should be using by now, no?

2010-2020 will be know as the decade that ended Moore law.

Actually, it's proof that Moore's law is still going strong.

Moore's law was never about *faster* CPUs, it was about more transistors per mm² on the die.

For several generations, more transistors did turn out faster CPUs. Bigger caches, better branch prediction, µOp architectures - and by coincidence faster clocks.

The "faster clock" thing is hitting a ceiling, so new CPUs work to increase the instructions-per-cycle. One big way this is done is to extend the MMX/SSE SIMD instructions to wider and wider registers, with more complete instruction coverage.

AVX uses 256-bit wide registers, with good FP coverage and basic integer instructions. This is basically "loop unrolling" in hardware. A single instruction can do 8 FP32 or "int" operations in parallel.

AVX2 extends AVX so that the 256-bit registers can do a fairly full set of both integer and floating instructions. AVX512 doubles the size of AVX2 registers to 512-bits - so each instruction can do 16 FP32 or "int" operations.

There are also new instructions to accelerate encryption/decryption and other tasks.

But, this all goes to waste if your programs are still compiled for Woodcrest 65nm processors.

Actually, I disagree. The SE/30 was an all in one machine and had limited expandability. I had one. Upgraded the RAM, and ran a second Black & White (not monochrome) monitor. Couldn't do much else.

IMHO, the cMP 5,1 is the modern Macintosh II (the first really expandable Mac). I had a IIci, Processor upgradable, NuBus slots and etc.

My Score - 2272

My sister bought a 4 core mac mini 2018. She uses Tesseract for OCR. Her new machine is quite bit faster at that task than my 3.5 Ghz 2014 iMac. I suspect that AVX-512 is a big part of that.

What is the configuration of the Z800? As an FYI the Zx00 series uses similar levels of technology as the 4,1 and 5,1 Mac Pros.
