That also have 3GB RAM and eMMC, or am I missing something?

  I didn't notice before that Librem 5 doesn't have HW accelerated video encoding. Looks like most of the performance difference is in GPU. CPU is the same old Cortex A53 in both.

    The speed of RAM is another big difference.

      Yes, and I also like USB 3 on Librem 5. Anyway, that table seems a bit inaccurate in a few places. Video out on USB-C is not limited to 1080p, cameras are not using MIPI CSI but parallel interface, not sure how to interpret meaning of 4 channels in the codec (it's a stereo codec, so mostof the paths have 2 channels, L/R and number of inputs/outputs is way larger - in the range of 20 or so), also it's not limited to 48kHz, but to to 192kHz.

        Hi megous, I created the spec table comparing the two phones. The "2.7. Image In" section on page 10 of the A64 Datasheet (https://files.pine64.org/doc/datasheet/pine64/A64_Datasheet_V1.1.pdf https://files.pine64.org/doc/datasheet/pine64/A64_Datasheet_...) calls MIPI CSI a "8bitYUV422 CMOS sensor parallel interface". Are you referring to that parallel interface or something else? -------- 2.7. Image In CSI •Support 8bitYUV422 CMOS sensor parallel interface •Support CCIR656 protocol for NTSC and PAL •Maximum still capture resolution to 5M •Maximum video capture resolution to 1080p@30fps ----- I see that I was mixing up inputs/outputs and channels. The A64 supports 4 inputs and 4 outputs, but only two channels in the DAC and ADC. I see that the DAC supports 8 - 192 kHz, but the ADC only supports 8 - 48 kHZ. OK, I'll clarify that in the table. ----- 2.8.Audio Subsystem Audio Codec •Two audio digital-to-analog(DAC) channels •Stereo capless headphone drivers: -100dB SNR@A-weight -Support DAC Sample Rates from 8KHz to 192KHz •Support analog/ digital volume control •Differential earpiece driver •Analog low-power loop from line-in/microphone to headphone/earpiece outputs •Support Dynamic Range Controller(DRC) adjusting the DAC playback output •Accessory button press detection •Four audio inputs: -Twodifferential microphone inputs -One differential Phone input -Stereo Line-in L/R input •Four audio outputs: -Earpiece amplifier differential output -Phone amplifier differential output -Headphone amplifier L/R channel output -Line-out L/R output •Two audio analog-to-digital(ADC) channels -96dB SNR@A-weight -Supports ADC Sample Rates from 8KHz to 48KHz •Support Automatic Gain Control(AGC) and Dynamic Range Control(DRC) adjusting the ADC recording output •Two PCM interface connected with BB and BT •One 128x24-bits FIFO for data transmit, one 64x24-bits FIFO for data receive •Support Audio HUBI -----

        Terminology around camera sensor interface module is confusing. MIPI CSI is supposed to be a camera serial interface. Cameras on Pinephone are connected via a 8-bit parallel interface. I'm also not sure how they came up with 5Mpix in the datasheet, CSI can do up to 4800x4800 which is 23Mpix. OTOH, 1080p@30fps is not attainable on the parallel interface, at least not with the cameras that are in the phone. It would require ~120MHz clock, and communication starts to break down at around 60-70MHz.

      Overall it's just a little bit less atrocious.

      Yeah, from my experience the speed of RAM makes the biggest difference in regular usage. It's especially visible in GTK apps which perform noticeably better on the Librem 5. Compilation times on L5 are also much shorter. GPU is another factor, but obviously that matters only in GPU-heavy workflows, like games (or at least should, there are still some optimizations in phoc to be done ;)). From obvious things that matter a lot in regular usage I'd also mention that L5 supports 5GHz WiFi that PP doesn't (and I've already seen some places with 5GHz-only WiFi), and its screen is much prettier (colors and blacks - I don't have many objective measures, but the difference is obvious in person).
