<p>My uneducated guess says, not much. For running massive models you still need a ton of high-bandwidth interconnects between many individual chips/GPUs/etc since you need to do math across a few TB worth of weights. That's simply going to require more power (and more die area in I/O, and therefore more cost). Being able to run small models in tiny power envelopes is incredibly useful to people, but I believe it will be covering a different niche than what datacenters can provide. Likewise, you'll still need crazy amounts of high-end memory to populate whatever goes in these datacenters.<p>The only thing that will crash prices is reduced demand (duh) or, more interestingly, increased production. In particular, if CXMT is able to get their DDR5 fabs up to a reasonably high yield, that could add some downward price pressure (as could government subsidies). As well, if Micron/Kingston/Hynix think that CXMT is going to start cutting into their market share, they might be willing to either increases supply or drop prices. Unfortunately CXMT looks to be taking quite a while to get their new fab up to max capacity so that may take a year+ before anything manifests.<p>If you're interested in following the (publicly available) info on these sorts of things, check out what companies like Axelera, DeepX, and MemoryX are doing today and have on their roadmaps, as well as the sorts of chips/SoCs Qualcomm, Kinara (now NXP), and Ambarella currently have announced (or have on the market). And remember, that pretty much all of these chips on the market today were in initial development more or less when ChatGPT first launched. If you knew what you knew today (or a year ago) about what requirements current- and next-generation models would have (from a silicon perspective), what might you do differently? Think for instance, host system interconnects, amount and speed of on-package or on-die memory, image/video decode capabilities, int8 vs fp8 vs fp16 vs bf16 compute units, etc. And, consider that most "AI" stuff in development a few years ago was all 15nm or 12nm - because who was gonna pay big money to get fab capacity at 3nm to run some object detection models? So most of the stuff on the market today is on very old nodes and therefore not super power efficient.</p>

<p>> ECC DIMMs are available only for the memory speeds guaranteed to work by the manufacturers of CPUs, like Intel and AMD, e.g. for up to DDR5-5600 in UDIMMs or DDR5-6400 in RDIMMs.<p>This is not true[1]. These DIMMs are not guaranteed to work with all Threadripper CPUs, but they are guaranteed themselves to be stable at their advertised frequencies, which are higher than JEDEC. (And from my experience, 9000-series threadripper is perfectly happy to drive 8-channel 1Rx8 at 7200MT/s.)<p>AMD (and possibly Intel, I don’t have any experience with their recent offerings) also lets you overclock memory completely on WRX90. So if you buy JEDEC sticks, you’re welcome to try to push them as hard as you can.<p>[1] <a href="https://v-color.net/products/ddr5-ocrdimm-amd-wrx90-workstationmemory" rel="nofollow">https://v-color.net/products/ddr5-ocrdimm-amd-wrx90-workstat...</a></p>

<p>There are absolutely fast DDR5 ECC DIMMs[1]. Just break out your wallet (and piggy bank, and rainy day fund, and..)<p>The main reason there aren’t more options here is that a) high-frequency memory usually isn’t sufficiently stable, unless binned, and b) there’s very, very, very little demand.<p>[1] <a href="https://v-color.net/products/ddr5-ocrdimm-amd-wrx90-workstationmemory" rel="nofollow">https://v-color.net/products/ddr5-ocrdimm-amd-wrx90-workstat...</a></p>

<p>I’ve been running a Supermicro X10SLH-LN6TF as my router, and it’s very well suited for the job. Power use is very high for a home router, but reasonable for a 1U router - especially considering the era it’s from and its capabilities (routing 5-8Gbps per stream depending on firewall config, able to handle a couple active streams, and line rate routing with no firewall).<p>I wouldn’t suggest anyone buy something like this today for home use, but 6 years ago when I purchased it there were not many 10GbE routers to be had period, let alone for the price ($300 roughly if I remember correctly ). Even considering the cost of power over the last 6 years, I still come out much cheaper than if I’d bought something more power efficient new at the time.</p>

<p>In ~300k km worth of diy oil changes, I’ve yet to change a crush washer, and yet to have a drain plug leak.<p>I always replace them on friends’ Toyotas, because they seem more important, but on every car I’ve owned it hasn’t mattered. And if you take the least amount of effort to google “how to change oil on ________” (fill in the blank for your year, make, model), some forum or video will probably tell you exactly what steps to take, including whether or not changing a washer is necessary.</p>

<p>Changing oil requires<p>> a place where you have sufficient access to the vehicle to drain it<p>Probably the only valid argument for people who park on the street.<p>> the right equipment<p>One $5 wrench, one $10 filter wrench (optional). One set of ramps ($40), or jack stands ($30) if you already have a jack. One drain pan, $10 (or free if you're resourceful). Total cost max $65. Cheaper if you look for deals, buy used, borrow from a friend. If you can't afford $65 once to save money in the long run while owning a car, you probably should've bought a cheaper car.<p>> the right disposal solutions<p>Every oil change requires a jug of oil to be purchased. You can drain your used oil into this jug and then dispose of it along with your other household hazardous waste. This is not hard.<p>> Most people who have cars do not have that.<p>I <i>might</i> believe this for a place to do an oil change, maybe. I struggle to believe most, but I would believe many. Aside from that, if you don't have those things, you are choosing not to have them.<p>Which is kind of the point. None of these things are hard, <i>at all</i>. The majority of car owners 100 years ago could adjust their own timing, clean distributor points, replace belts, etc. because if they couldn't, they'd be calling for a tow truck every few hundred miles. Those are all harder, and things have only gotten easier with time. If you can't do them, you are choosing not to, because there's an even easier solution - spending more money and getting someone <i>else</i> to do it for you.</p>

<p>I agree. I ran mid 16s in 8th grade, and was in the 14s in high school, with the only training being whatever we did in gym class. But I do also look at the sheer number of overweight kids these days and figured, well maybe mid-16s is actually a reasonable average point.</p>

<p>> Very few mere mortals could run that fast for even 100m.<p>That works out to roughly a 16.7-second 100m. While certainly not crawling, that would be a fairly average pace for a fairly fit middle- to early-high-schooler with a bit of practice.<p>Yes that’s insane to maintain for a marathon, but it’s not even remotely out of reach for 100m for most relatively-fit people at some point in their lives.</p>

<p>I’ve mentioned this as an option in other discussions, but if you don’t care <i>that</i> much about tok/sec, 4x Xeon E7-8890 v4s with 1TB of DDR3 in a supermicro X10QBi will run a 397b model for <$2k (probably closer to $1500). Power use is pretty high per token but the entry price cannot be beat.<p>Full (non-quantized, non-distilled) DeepSeek runs at 1-2 tok/sec. A model half the size would probably be a little faster. This is also only with the basic NUMA functionality that was in llama.cpp a few months ago, I know they’ve added more interesting distribution mechanisms recently that I haven’t had a chance to test yet.</p>

<p>I stopped getting scared of `if` and `of` about a decade ago when I started explicitly saying (in my head) "input file" and "output file" rather than "if" and "of." You still can mess up the order, but imo no more easily than you can swap `cat in > out` for `cat out > in`.<p>> Friends don't let friends use `dd` where `cat` can do the same job.<p>Technically yes... but I like being able to explicitly set block sizes and force sync writes.</p>

<p>You can however set the block size to something quite large, which means you write the same random pattern <i>spread out over multiple blocks</i> repeatedly. If you pick an "odd" block size (like say, your native block size multiplied by 47), it's highly unlikely your disk under test will be swapping around "groups of 47 blocks." (I usually just do a nice multiple, like 4K<i>16, but if you're super paranoid a weird multiple should be pretty much good enough). You won't get reporting of which </i>exact* blocks on the drive are failing, but these days, that isn't really useful information - if any blocks are failing, warranty or ditch the drive.</p>
