7 - Performance Mandel FPU test | HD Tach 3.0.4.0 | Power consumption

 

Mandel FPU test

The Mandel FPU benchmark measures double precision (also known as 64-bit) floating-point performance through the computation of several frames of the popular "Mandelbrot" fractal. The code behind this benchmark method is written in Assembly, and it is extremely optimized for every popular AMD and Intel processor core variants by utilizing the appropriate x86 or SSE2 instruction set extension.

Now if you come from the Commodore 64 / Amiga era like me, you can probably remember rendering Mandelbrot graphics, and it took a full day to complete an image. Amazing where we are right now as the same set of calculations can be done in seconds & even real-time.

The FPU Mandel test again is HyperThreaded, multi-processor (SMP) and multi-core aware. Okay so we established that you are not having the best Floating point crunching machine at hand here :)

HD Tach 3.0.4.0

HD Tach is a physical performance hard drive test that uses a special kernel mode VXD to get maximum accuracy by bypassing the file system.

The HD Tach sequential read test is a little bit different from other benchmarks.

Now I ws afraid that such a low specced PC would have a nasty large impact at SDD performance. it's not the case. Compared to a 680i SLI mainboard with quad-core Q6600 processor we only loose 8.7 MB/sec in read performance. And that was at 3% CPu utilization. Really lovely to see

In addition to sequential read, HD Tach tests the drive's random access time. Random access is the true measure of seek speed. Many drives advertise sub 10 millisecond seek speeds, but seek speeds are misleading. Also again, without a head that needs moving around, the SSDs are just so fast. Here obviously .. the smaller number  means better. Obviously also here it was close to NIL at 0.4ms access times.

HDD / SDD performance wise you will benefit greatly from fast storage on a platform like this, and you can rest assure that the Atom 333 based PC will not be a limiting factor at all.

Power consumption

Alright then, let's monitor something besides performance... power consumption.

With all the high-frequency and quad core madness lately, we are getting used to power consumption levels of 200 to 300 watt per PC these days.

The Atom 330 Dual core processor utilizes ... and do get scared now .. 8 Watt at maximum :)
When I power off my PC and switch off the PSU, it still uses 25 Watts. So that Processor power consumption is just nothing.

For the entire "PC" we maxed out at56 Watt with both CPU cores 100% stressed and the PC in idle consumed 43.6 Watt. The light bulb in my toilet uses even more power.
