Computers and studio gear Mon, 17 Feb 20 09:45:53 +0000 Computers and studio gear en-CA Intel Xe and their discrete GPU Fri, 22 Mar 2019 00:41:32 +0000 Vitaliy_Kiselev 21762@/talks/discussions image


Intel posted first images of their discrete GPU.

Lot of industry press post various bullshit on how competitive it will be and such.

In reality here we see 75-120W card with worst possible cooling, obviously made for multi GPU configurations.

Real intended market for this card will be CAD, 10-14bit color editing and similar applications.

GPU itself won't be really powerful.

Whole project is more like a con to distract public from full failure with moving to real 10nm and 7nm.

Meet the future - how most MB will look in 5 years time Tue, 21 May 2019 00:22:31 +0000 Vitaliy_Kiselev 22090@/talks/discussions image

This one is for Xeons.

Yep, 2 CPUs, 6 channel memory for both. 7 full size slots can be absent in cheap consumer MB, but all else will be same.

Intel and AMD still want to trick people, just watch new 16 core AMD testing guides and how reviewers will tell you how nice is to have 2 channel memory (if you properly select benchmarks) . :-)

Idea is to move to 10 cores using same 14nm process, making it even larger die.

VRM requirements and heat output will also increase.

And, as usual, for each generation we will see new socket.

DRAM selection for Video Editors Thu, 21 Mar 2019 03:50:16 +0000 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.

  • All lines provided by chipset will be PCIe 3.0 or PCIe 4.0.
  • Number of provided lines will rise by 25-50%
  • It'll have 4 USB 3.1 Gen2 ports controller not requiring additional Asmedia chips and supporting part of power delivery standards.
  • We can see build in 10Gbe network controller (that will still require additional chips and transformer).

    Lenovo: Story of idiots Mon, 21 Jan 2013 09:08:05 +0000 Vitaliy_Kiselev 5856@/talks/discussions image

    Lenovo will continue to destroy all advantages of ThinkPad design.

    They do it one by one:

    • 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.

    Btw, Ideapad brand will be destroyed as complete failure. And ThinkPad will be widened to try to sell all their crap.

    My IBM 600e looks like something made by alients compared to my modern ThinkPad.

    Older Ryzen processors for editing rig Sat, 06 Jul 2019 04:12:10 +0000 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

    ATX12VO cheaper PSUs coming soon, designed to make MB unrepairable Thu, 23 Jan 2020 07:11:19 +0000 Vitaliy_Kiselev 23420@/talks/discussions

    According to the specification, the PSU only puts out +12 V and 12 Vsb voltage domains, and does away with the 5 V, 5 Vsb, and 3.3 V domains. This greatly simplifies the design of PSUs, as PCs of today don't use too many power-hungry 5 V or 3.3 V devices (such as half-a-dozen mechanical hard drives). The PC will still need 5 V for interfaces such as USB, but VRM on the motherboard will be responsible for DC-to-DC switching of 12 V to those lower-voltage domains. It's also likely that the motherboard will now put out a handful SATA power connectors.

    It is total bullshit about "great simplification", as all good PSUs already make 3.3V and 5V using DC-DC small boards. 5Vsb is also being made by specialized tiny controllers.

    Before implementation of DC-DC converters inside PSUs 5V and 3.3V failures had been very rare, usually all devices survived. Now serious failure put 12V on this rails, so say bye-bye to your SSDs and HDDs, as well as almost all devices on MB. But at least this DC-DC boards in good PSUs are monitored using separate controller (so switched off instantly in case of issue) and good cooled. Placing them directly on MB will lead to making things much worse.

    Idea of both PSU and MB manufacturers is to cheapen construction and go away from protection schemes (to further increase profits).

    MB manufacturers are especially hoping that such designs will allow them to make product that will kill itself in 3-6 years time (usual life of cheap polymer caps they'll use).

    Sandy Bridge - old but usable, even for 4K Wed, 14 Jun 2017 06:26:58 +0000 Vitaliy_Kiselev 17145@/talks/discussions For starters small tip. Not all guys know that you can overclock even non K models, if on proper MB.


    Usually it is enough to use build in MB automatic feature.

    On average it'll be 3.8Ghz for 4 cores mode + 103Mhz BCLK, overall it is 15% performance rise (it takes Intel around 4 CPU generations now to do same :-).

    In reality, of course it is simpler to get i2500K for around $51.5 (like Z77, P67 does not support it)

    Around 95-99% of CPUs work perfect at 4500Ghz, and around 30-40% on good cooler can work at 4.8-5Ghz.

    Overclocked Sandy Bridge with GPU like 1050 / RX 460 still is cheapest build for 4K editing, especially with proper editor.

    TRX40 chipset diagram


    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,
