Sabrent Rocket NVME SSD inside One-Netbook A1

Sabrent Rocket is one of the fastest NVME SSD series in the formfactor of M.2 2242. According to the manufacturer, "its speed performance can reach up to 2500MB/s read and 2100MB/s write" (ref).
Here is what you can expect from this SSD inserted into the One-Netbook A1 handheld computer:

It’s worth mentioning that the default One-Netbook SSD shows very similar performance.

So there is no reason to replace SSD in order to get higher speed. The default SSD is pretty much the best you can achieve.

Benchmarking UMPCs of the second epoch

Introduction

"An ultra-mobile PC (ultra-mobile personal computer or UMPC) is a miniature version of a pen computer, a class of laptop whose specifications were launched by Microsoft and Intel in spring 2006." (c) Wikipedia. That was the dawn of the first UMPC epoch. This epoch did not last too long, because in the early 2010s major UMPC manufacturers ended its product lines. Few years later new manufacturers emerged and recreated UMPC market. The major one was the Chinese company GPD. GPD started the second UMPC epoch by releasing gaming handheld GPD Win in 2016 and the general purpose device GPD Pocket in 2017. Since then a whole bunch of UMPC devices were released. In this article we will compare performance of various UMPC devices from the second epoch: including the very first GPD Win and the most powerful UMPC up do the date – One-Netbook OneGx1 Pro.

Disclaimer. This article is not a comprehensive performance analysis of the 2-nd era UMPCs. All the test items are taken from my collection. Therefore the number of test items is quite limited. In case I add any new corresponding items to my collection, this benchmark survey might be extended as well.

CPU & Memory performance

PassMark Performance Test results
Geekbench test results
CPU-Z test results

The 11th generation Intel Core mobile processors (codename Tiger Lake) is a substantial breakthrough. It’s hard to believe that Core i7-1160G7 is faster than the high-end desktop processor Core i7-4790k, which was discontinued in 2017.

SSD performance

CrystalDiskMark test results

It is worth noting the variation in write speed across devices. Write speed of premium OneGx1 is significantly lower than the write speed of A1.

3D performance

3DMark test results
Unigine Heaven test results

Few notes:

  1. Performance of Iris Xe is just outstanding.
  2. Tiger Lake supports Thunderbolt 4, which allows to connect gGPU to the UMPC. eGPU can improve 3D performance of OneGx1 Pro by at least 4 times. See details here: Benchmarking OneGx1 Pro with eGPU.
  3. Performance of A1 is significantly lower than performance of OneMix 2s, which is based on the same Intel Core m3-8100Y.

Conclusion

Since GPD Win performance of UMPCs has increased in many times in every single aspect.
Tigre Lake architecture is an outstanding breakthrough in both CPU and GPU performance.

Benchmarking OneGx1 Pro with eGPU

I connected EVGA GeForce GTX 1080 FOUNDERS EDITION to One-Netbook OneGx1 Pro via the following eGPU box: Sonnet eGFX Breakaway Box 550.

Here are the main results:

  1. eGPU can improve 3D performance of OneGx1 Pro by at least 4 times.
  2. Performance of the video card inserted in the desktop is significantly higher than performance of the same card connected via eGPU box.
  3. Performance of eGPU is significantly higher when the image is displayed on an external monitor.

More benchmarks of OneGx1 Pro are availavle here.

GPD MicroPC arrived

Overall impression

MicroPC looks very robust. The build quality is quite impressive. Chinese companies definitely improve their skills. The keyboard is one of the most comfortable handheld keyboards I’ve ever used. The size of the device is significantly smaller than size of similar devices from UMPC era (see comparison photos below).

In general I really like the device. I can’t mention any disadvantages so far.

I did’t like the original GPD case, because it’s designed to fit much larger devices (GPD Pocket, probably). So I ended up using the FlipStart bag instead, because I have an extra one and the MicroPC fits perfectly.

Benchmarks

The performance of MicroPC is significantly higher than the performance of Microsoft Surface 3.

DOOM 3 benchmark (1280×720, graphic quality set to high, timedemo demo1)

Device FPS (1st run) FPS (2nd run) FPS (3rd run) Average FSB
GPD MicroPC 10W 39.5 44.6 47.0 43,7
Microsoft Surface 3 30.5 31.7 34.1 32,1

It’s also worth mentioning that Surface 3 is unable to sustain this perofrmance during long period of time. Without active cooling Surface 3 starts throttling and the performance decreases to 23-24 FPS.

Benchmarking Toshiba Libretto 70CT

Introduction

Toshiba Libretto 70CT is based on Intel Mobile Pentium MMX 120 Mhz (sSpec number SL2JS). Lets compare this this processor with a desktop Pentium MMX of the same time:

Model number Lithography Frequency L1 Cache FSB TDP sSpec number
Mobile Pentium MMX 120 0.35 µm 120 Mhz 16+16 KiB 60 MT/s 4.2 W SL2JS
Pentium MMX 166 0.35 µm 166 Mhz 16+16 KiB 66 MT/s 13.1 W SL239, SL27H

Despite being built using the same lithography technology as the desktop Pentium MMX processors (0.35 µm) and having comparatively close frequency (the desktop processor has 38% higher frequency), SL2JS has significantly smaller TDP (the TDP of the desktop processors is 3.12 times higher, than the TDP of SL2JS).

Because of this fact I became curious whether the performance SL2JS will be identical to the performance of a desktop MMX processor with the same frequency of 120 Mhz. In order to find this out I prepared a test setup and executed few CPU benchmarks. The benchmark results are presented below.

Testing methodology

The following programs were used to test CPU performance:

  • SiSoft Sandra version 2001.0.7.10;
  • PassMark Performance Test 5.0 build 1038;
  • CPUBENCH version 4.0.0.6;
  • Speedsys version 4.78;
  • Landmark System Speed Test version 6.00;
  • Norton System Information 8.0;
  • Quake version 1.0.6. Settings: resolution is 320×200, disabled sound, disabled cdaudio, demo1 used as demo map. Full config is available here.

All tests performed after suitable warm-up period.

Setup #1 description

Toshiba Libretto 70CT

Device: Toshiba Libretto 70CT
BIOS version: 6.40
CPU: Mobile Pentium MMX 120 (SL2JS)
RAM: 32Mb (including genuine 16Mb extension module)
Video: Chips & Technology F65550 1Mb
OS: Windows 98 SE 4.10.2222 A

Setup #2 description

Intel Pentium MMX 166

Motherboard: Lucky Star 5I-VX1F
BIOS version: 4.51PG
CPU: There is no desktop Pentium MMX clocked at 120 Mhz. Therefore a downclocked Pentium MMX 166 was used (clocked at 120 Mhz with 60 MHz FSB). There were used two samples with different spec numbers: SL239 and SL27H.
RAM: Hitachi 32Mb SDRAM 81117822a-100fn
Video: S3 Trio64V2/DX 2 Mb
PSU: Linkworld LP12SWITCH 200W
OS: Windows 98 SE 4.10.2222 A

Test results

Landmark System Speed test results

Speedsys test results

Norton System Information test results

As we can see, DOS benchmarks didn’t detect any difference. However, Windows benchmarks show a different picture.

PassMark Performance Test results

SiSoft Sandra test results

CPUBENCH test results

In most tests the SL2JS is behind its desktop competitors. In some test the gap is as big as 49%, but the average difference is only 10%.

I also decided to execute one additional test with Quake. However, the results of this benchmark can not be linked directly to CPU. This benchmark is highly dependent on video output and there are different video chip used in the test
setups. Anyway, here is the result.

PassMark Performance Test results

Conclusion

The presumption was confirmed. The performance of SL2JS is not identical to the performance of a desktop MMX processor with the same frequency. However, the average difference in performance is not very significant: it’s just 10%.

Cortex-A8 vs Coppermine

Samples description

I made a few benchmarks of two devices:

  1. The Pandora device (based on OMAP3530).
  2. A PC with 256 Mb SDR RAM and one of the following CPUs: Pentium 3 and
    Celeron.

Both systems used the same gcc-4.4.3 and glibc-2.11.2.
Whole systems were compiled with the following flags:

PC flags:

CFLAGS="-O2 -march=native -pipe"
CXXFLAGS="${CFLAGS}"

Global USE includes sse and mmxю ffmpeg’s use uncludes mmxext.

OMAP flags:

CFLAGS="-O2 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp -ftree-vectorize -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

OMAP’s DSP was not used.

Legend

  • OMAP@600 is OMAP3530 running at 600Mhz (default for Pandora).
  • OMAP@850 is OMAP3530 overclocked to 850Mhz.
  • P3@600/133 is Pentium 3 EB (the Coppermine core) running at 600 Mhz (FSB clocked at 133Mhz).
  • Cel@600/66 is Celeron (the Coppermine-128 core) running at 600 Mhz (FSB clocked at 66Mhz).

Compilation

I want to emphasize that it is not a performance benchmark, because compilation is done for different architectures (ARM and x86). It is a benchmark of one particular task, which is essential for gentoo users.

package OMAP@600 OMAP@850 P3@600/133 Cel@600/66
binutils-2.20.1, m:s 37:50 28:45 20:06 28:23
glibc-2.11.2, m:s 177:27 138:19 104:09 145:16

OMAP3530 overclocked to 850 Mhz is very close to Celeron running at 600 Mhz.

Nbench

Nbench is a synthetic performance test.

The used version: nbench-2.2.3-r1
