...Seasonic do 1300w (got two of those) and also 1600W. But long story short, depending on your location (power system), Superflower Leadex 1600w or 2000W Platinum will be my next choice once the new connectors are available from them... tip #25: washer/dryer outlets often have 220/240V, even in 110V counties, otherwise it will be the 1600W...

...yes, I'm also surprised at that limit, though it probably has more ocp headroom for transient spikies. In addition, only one 12 vhpwr connector ? Gala HoF owners (3090ti below, 4090 to come) won't be pleased

...a quick 'FYI' tip for mounting external D5 pumps to control noise and vibration. D5s are generally among the quietest pumps out there to begin with, but when mounted on bare metal such as a wall of a typical PC case, it can become a bit of a harmonic frequency 'buzz' issue. Many CPU and GPU boxes along with CPU and GPU w-cooling block boxes come with both soft foam and harder rubber as packaging material which is great to mount between the foot of the D5 holder and the metal case - see arrow below in the first pic during a layout / test mount. Some free-standing D5s even have a custom-cut rubber piece included to act as a noise and vibration damper. Either way, even running 5x D5 can be made to be perfectly quiet and full speed, unless the pump itself has a bearing issue, or trapped air.

...easypeasy

...same VRAM re. 6800 and 6900, but when it gets to 550GB/s, there's this:

As posted before, I see no 'use case' reason for me right now to upgrade to a 4090 as among other things, I first want to see what the 4090 Ti and the AMD 7900XT/X bring to the table in real-world testing by several sources. The AMD NVidia matchup early next year should be a really interesting development as it pits a monolithic super heavy-weight die (4090 w/ ~ 78 billion transistors, 3090 w/ ~ 28 billion) against the new-gen mGPU chiplets - I am convinced that AMD will compete against the 4090 Ti with a multi-chiplet approach just like it did with Ryzen on the CPU front...it filed related patents a while back which describe how multi-chiplets in a GPU appear as a single GPU to the OS and drivers (so no Crossfire / SLI profile requirements). Ultimately, chiplets will win over monolithic also for cost and manufacturing reasons. Whether this will occur with the 4090 Ti / AMD XTX matchup or later, I do not know, but it will come to pass, IMO. In the meantime, NVidia will try to keep its crown and get more of our monie$ with exclusive software and driver trickery. Somewhat related re. upgrade plans, I always ran SLI or Crossfire over the last decade, w/o any real issues in at least the apps and games I have...but that upgrade path is clearly not an option anymore. So I just have to do with my trusty 'Ravens' eyes' for now

...I saw those earlier - but all it did is water my mouth for a 7950X 3D Vcache on a full custom loop

...I water-cool all CPUs and GPUs anyway, but with a 500W card (up to 675W when looking at some of the RTX 4K specs), it would be foolish not to, what with boost algorithms <> temps and all that. Also, PCBs are shrinking - below is the latest NVidia H100 (enterprise-level) with way > 500W. It is even smaller as it carries yummy HBM3 but on the consumer 4090s (& presumably 4090 Ti) w/GDDR6X, the PCBs have been shrinking also as VRAM is moved inwards and much closer to the chip die, and the phases have become even more powerful. Anyway, unless for 'artistic expression', I figure that most vendors' full water-block models (and aftermarket suppliers) will conform more or less to the (reduced) width of this gen's PCB. I think it is a great idea to have a full copper block covering the whole thing, and all within 200 mm

...now I really want to see some spy pics of the not-to-be EVGA 4090 FTW3, so that I can compare '''beauty shots''' w/ below. Custom water-blocks to the rescue @Bastiaan_NL ....get one of these inno3D 4090 Frostbite (only 200mm wide) and put it into an Asus 670E Gene w/ DDR5 A-die

...I run both a 6900XT and a RTX 3090 (work and play, but somewhat interchangeable functions) and yeah, the 6900XT in ray tracing is at about the same as one of my older 2080 Tis - so not bad, but it can't compete with the 3090 in RTX. If anything, the narrower memory bus of the 6900XT is a bigger issue at 4K across the board. I am certainly hanging back until early next year re. any potential upgrades (unless I change my mind and do the opposite...). So far, Nvidia's 'numbers' on performance gains are basically 'apples to oranges', ie. DLSS 3.0 vs no DLSS at 8K etc. I figure around 60 -70% genuine improvement over for example my oc'ed 3090, but that card is already giving me joys even at max 4K OLED. So since there's no immediate need, I might as well see what the 4090 Ti and/or 7900XT(X) are all about for a bigger jump.

...good point about DLSS being more important in the mid-range cards. Then again, the few demos I've seen on 4090 w/ DLSS 3.0 and RTX all seem to point at 8K...looks like NVidia is trying to push that one (8K) again. On the mid-range front, though, I find it telling that NVidia is releasing the 'weaker' 4080 with the gimped memory bus and reduced core count; in earlier and otherwise accurate leaks (re. 4090, 4080 16 GB), that model was actually tagged as a 4070. May be NVidia is expecting more competition in the mid-range from AMD and even Intel (once Intel sorts its vbios and driver problems) and wants to inject a reconstituted 4070 into that battle, especially during weaker economic times and associated consumer budget concerns ?

...but not if it goes by size / weight

...looks like good tech (withheld from RTX3K - for now at least), but until I see a pile of independent tests by trusted sources, I'll have the 'salt shaker' ready. The YT below claims both RT on / off on the left, no to mention no DLSS (2?) at 8K on the left...duh

...yeah, there's no magical slowdown upon release of a new CPU (though current GPUs have experienced some funny stuff with new drivers for next gen - looking at you, NVidia ). The speed on both Raven_A systems is good enough that I rather wait until early next year before planning any HW upgrades...I really like to first find out more about GPUs, ie. both the 4090 Ti and the rumoured XTX7900 (mGPU with up to 48 GB, 24k cores). On CPU, Raptor Lake 13900K looks decent but it apparently is just a stand-in due to Meteor Lake being behind schedule. The 7950X >> AM5 socket on the other hand is supposed to stick around for a few years. Bonus: AM5 will accept my specific AM4 w-blocks (Phanteks). ...since I stopped my HWBot activities, no need to hurry re. buying the latest gen...

...fiddled a bit more with a few more optimizations and unlike the Cinebench R23 score of 32,439 above which is near max on water for this particular 5950X chip, below is my new 24/7 daily 'summer' setup, complete with a small undervolt and utilizing the DynamicOC function on the Asus DarkHero. Under load, vCore is around 1.18 for all-core, and to get almost 32k in Cinebench R23 at just 210W CPU package power (max I've seen before in full battle dress is over 260W) is great - and reflected in temps as well. At this rate, the new 7950X can wait a bit

...perfect weather for a flight at dusk to Mt. Baker (Washington State) which, weather permitting, I can see from my home office

...the 256 bit wide bus of the 6900XT was already found to be a bit tight (even w/ infinitycache) at 4K (&+)

I'm sure that he was born ready for cold-induced extra speed ...wouldn't surprise me at all if Bastiaan has some hefty copper ingots scurried somewhere & ready to machine his own sub-zero pots....

...I love that stuff - easy to work with, but holds its shape. Certain types of cooling, eh ? Air > water > chilled water > DICE > LN2 (> and possibly liquid helium)

...this stuff is great to make the weirdest supports and mounts out of :

...I use two of these risers (PCIe 4.0) with no loss in performance per my own tests on 3090, and also 6900XT. With some rejigging, it should work for your SLI / NVLink and two w-cooled 3090s.

....yeah, 192 bit bus ...looks like my 3090 Strix (w/ up to 1kw custom bios and 384 bit bus / 24GB VRAM) will be it for me for a while yet. I am likely to skip the 4090 and wait for the 4090 Ti (or AMD's rumoured XTX 7900)...

...I put Igor's A-die summary / link > here last Monday. The oc room he's getting is very promising !
