Apple MacBook Pro 16, most expensive overheating gadget http://webmail.personal-view.com/talks/discussion/23065/apple-macbook-pro-16-most-expensive-overheating-gadget Wed, 13 Nov 2019 10:44:05 -0700 Vitaliy_Kiselev 23065@/talks/discussions image

Base system

  • 2.6GHz 6-core i7
  • 3072 x 1920 IPS display, 500nits brightness tops, slimmer bezels means much more broken screens
  • 16GB RAM (around $50 cost to Apple in parts, Apple asks $400 for it)
  • 512GB SSD (around $40 cost to Apple in parts, Apple asks $200 for it)
  • If you have any issue with SSD, it is impossible to restore data or repair SSD
  • Radeon Pro 5300M with 4GB GDDR6 (sic!) (around $70 cost to Apple in parts)
  • Return to old keyboard (aka ones used in other notebooks)
  • 100Wh battery, up to 11 hours of light video watching on low backlight
  • $2400, only around 2-2.5x of comparable Windows note
  • https://www.bhphotovideo.com/c/product/1520434-REG/apple_mvvj2ll_a_16_macbook_pro_late.html

Top system

  • 2.4GHz 8‑core i9
  • 3072 x 1920 IPS display, 500nits brightness tops
  • 64GB RAM (around $200 cost to Apple in parts)
  • 8TB of SSD storage (around $500 cost to Apple in parts)
  • If you have any issue with SSD, it is impossible to restore data or repair SSD
  • Radeon Pro 5500M with 8GB of GDDR6 (around $200 cost to Apple in parts)
  • Return to old keyboard (aka ones used in other notebooks)
  • 100Wh battery, up to 11 hours of light video watching on low backlight
  • $6100, at least this one is better and match current Apple smartphones margins

Cooling had been improved, but for top configs it is absolutely not enough with it's single heatpipes for CPU and GPU.
Even much cheaper Xiaomi Notebook Pro this year offers double the cooling with lighter heat output.
Horrible heat design again, Apple!

AMD moved to PCIe 4.0, almost ell else is downgrade from x399, for example it removes 4 PCIe lines going directly from CPU to SSD and reroute them to chipset.

It is ZERO reason to put 8 PCIe lines (and they are v4.0!) to such bad chipset and with CPU having so much PCIe lines by itself.

If you look at this you will see how mighty is CPU, but how shitty is AMD TRX40 chipset.

In reality it is even less features and more restrictions than consumer X570 one. But this allows AMD to get huge profits,

Keyboards http://webmail.personal-view.com/talks/discussion/2982/keyboards Mon, 23 Apr 2012 10:00:15 -0600 Vitaliy_Kiselev 2982@/talks/discussions While in camera world we have clear progress year after year, in keyboard business things in mass market are going in reverse.

If you get IBM PS/2 keyboard from 1991 and after working on it you go to your shop and try various keyboards you'll be in shock. Starting from $5-10 crap invented only to type up to 140 symbols a day (makes you understand twitter popularity), to pricey junk "space ships" designed to run video player.

And gaming keyboards. This is long story. Not only you must send all your time down the pipes, but you must do it on cool keyboards. I am not even start the story of motherfuckers who place extra keys in the bottom row, more and more. Inventor of Windows keys (and Fn keys on notebooks) must be found and executed in public using some very paintful way.

This was few thoughts I got after looking at keyboard market and getting Razor BlackWidow (not big choice of localized mechanical stuff is available really).

image

This is mechanical keyboard based on Cherry MX Blue switches

Razor keyboard is very good example of modern "inventors".

  1. Key size is slightly reduced compared to normal keyboards (whole main block is smaller than normal keyboard).
  2. Typeface used for keys is just awful, not major, really, if you type constantly, but anyway.
  3. As this is "gamers keyboard" it has macro keys that are on the left and placed in such distance that makes harder intuitive use of left Ctrl.
  4. It is glossy and keys are made from quite cheap plastic (if you compare to IBM keyboards)

But overall, of couse it can't be compared to rubber dome crap, even good one as some Microsoft keyboards.

It not have ideal main key block layout like some keyboards:
image

As Enter is still small.

May be in future we'll see something ideal, like IBM keyboards, but with larger bottom row, no widows keys and with buckling spring or mech switches options.

Note: You can get older (not 2013) version, it is cheaper but absolutely the same from practical standpoint

Older Ryzen processors for editing rig http://webmail.personal-view.com/talks/discussion/22258/older-ryzen-processors-for-editing-rig Sat, 06 Jul 2019 04:12:10 -0600 Vitaliy_Kiselev 22258@/talks/discussions Ryzen 3xxx processors are very nice and all, but financially they are not optimal budget choice outside top segment of 12-16 cores.

Compared to 1-2 gen Ryzen new CPUs real advantage is only around 10-15% on same clock speed, all Ryzen processors are overclockable on any decent motherboard.

So, we'll go from most bargain CPUs:

Two latest CPUs are best for file storage servers or for simpler 1080p editing rig.
Even Ryzen 3 1200 is enough for fast server with 10Gbit connection and pair of NVMe drives that hold most recent footage. Ryzen 1700 will be better and better each month, as Adobe and Resolve with each new release will be more and more aimed for high core CPUs.

I strongly suggest to use x370-x470 boards, even if used, to have upgrade path for later, check https://www.personal-view.com/talks/discussion/21405/amd-am4-motherboards-selection-guide-for-video-editors#Item_22.

    • Making construction cheaper and weaker
    • Horrible cheap materials now used for most models
    • Rock solid, best notebook keyboards first were made quite flimsy
    • Secondly keys were replaced to modern cheap ones
    • Famous very good IBM layout had been replaced by one used in cheapest IdeaPads
    • Now we can see fully removed TrackPoint buttons because some designer figured out that it'll be cheaper to force you press trackpad.

    PCI-SIG announced that PCI Express® (PCIe®) 6.0 technology will double the data rate to 64 GT/s while maintaining backwards compatibility with previous generations and delivering power efficiency and cost-effective performance. The PCIe 6.0 specification is actively targeted for release in 2021.

    PCIe 6.0 Specification Features

    • Delivers 64 GT/s raw bit rate and up to 256 GB/s via x16 configuration
    • Utilizes PAM-4 (Pulse Amplitude Modulation with 4 levels) encoding and leverages existing 56G PAM-4 in the industry
    • Includes low-latency Forward Error Correction (FEC) with additional mechanisms to improve bandwidth efficiency
    • Maintains backwards compatibility with all previous generations of PCIe technology

    image

    “PCI Express technology has established itself as a pervasive I/O technology by sustaining bandwidth improvements for five generations over two decades,” Dennis Martin, an analyst at Principled Technologies, said. “With the PCIe 6.0 specification, PCI-SIG aims to answer the demands of such hot markets as Artificial Intelligence, Machine Learning, networking, communication systems, storage, High-Performance Computing, and more.”

    “Continuing the trend we set with the PCIe 5.0 specification, the PCIe 6.0 specification is on a fast timeline,” Al Yanes, PCI-SIG Chairman and President, said. “Due to the continued commitment of our member companies, we are on pace to double the bandwidth yet again in a time frame that will meet industry demand for throughput.”

    Note that even EPYC Genoa (Zen 3 bases) will keep SP3 socket compatibility.

    So AMD abandoning TR4 socket is pure marketing bullshit decision, as sockets are physically same, except small wiring difference (plus SP3 has more pins used for additional memory channels and PCIe lines).

    Note that AMD revolution seems like go into a stop mode. As we'll see same cores, same SMT, same DDR4, just cache will be now shared.

    AMD states that they no longer aimed at any meaningful performance increase, but only (like Intel before) at reducing power consumption while keeping performance similar.

    DRAM selection for Video Editors http://webmail.personal-view.com/talks/discussion/21756/dram-selection-for-video-editors Thu, 21 Mar 2019 03:50:16 -0600 Vitaliy_Kiselev 21756@/talks/discussions Introductory note

    Memory is most blatant ripoff among all products related to computers.

    All, 100% of so called "gamers" or "overclockers" memory is based on same 2133Mhz or 2400Mhz chips as cheap DIMMS.
    Higher frequency chips are just selected among specific manufacturing batches aka dies. And sometimes not even tested properly (to save funds).
    For manufacturer main expenses for such kits lies in the bigger competition for select chips (can be up to $10 extra for 8GB DIMM), around $1-3 they spend on fancy alu heatsinks and $1-5 they spend on more colorful packaging. All else goes to pure profits, marketing expenses (can be large for small manufacturer), distribution and retail parts.

    Yet for many modern CPUs memory speed and timings greatly affect overall performance. And with each year such dependency increases due to lack of real progress in DRAM technologies. You can thank big patent troll named Rambus for lot of today issues.
