Very efficient, very very fast, no coil whine....
Well, what can you say? It is the fastest and most efficient card currently on the market.
I installed it directly in my custom Wakü with the Alphacool cooler. Disassembly very easy, gluing the thermal pads took the longest.
Directly screwed 100 Mhz on the GPU and 500 Mhz on the memory, the card does without problems. Card goes up to approx. 44 degrees at full load, but also has a correspondingly large radiator surface.
Consumes 100-150 less watts in the same scenario at the same frame rate than my 3080 Ti before.
At idle with 2 screens (34 and 27 inches), 10W consumption. Even then, my 3080 Ti was between 30-40W.
With the card, it's enough to set VSync, then it consumes much less and plays out its efficiency to the full. Value must have rendered more images than the screen can display? Or you can switch to 70%-80% power target, which is the most efficient setting anyway (just have a look at some tests on the net) and you lose almost no frames, with only about 320W consumption.
The card is really huge with the original cooler, but I've only read good things about the cooling performance and the noise.
I have no coil whine at all, absolutely top.
To all those who complain here... Card too heavy, too much consumption etc... If you bring these arguments, then you don't need the card anyway. And the price... Well, it is what it is and if you complain about it, then you shouldn't buy the card. A Ferrari costs more than a Seat Leon. To each his own. Above all, this card comes with a "holder" that you build into the case so that the card is "held" at the back and thus supported (less load on the PCI slot). So you don't have to be afraid of the weight.Pro
- Fastest card on the market
- Very efficient, less energy consumption for more power
- Huge cooler dimension, thus good cooling
- Additional fan to provide even more cooling capacity
- No coil whine
Contra
- Large housing necessary
Simply top!
I'll take the trouble of a more comprehensive assessment.
I have converted the Graka to a WaKü and even with this I have no coil beeping.
Alphacool water block has the same problem as the cable. And my case is already a Lian Li O11D.
In any case, I can only recommend switching to WaKü (see pictures, I would have liked to write, but the uploaded picture quality is sub-par).
Stress test 3DMark Speedway
After 8 loops:

- All the advantages of a 4090
- Good overclockability (113% Power Consumption Max without having to change or solder anything)
- Compatible with MSI Afterburner
- Nice software from KFA2 (I don't use it, but it still looks very valid).
- NO audible coil whine during normal operation
- Barely audible coil whine in 3DMark under full load
Contra
- Card is too wide, 12vhpwr cable is bent too much by the housing side cover, can be solved with adapter
Excellent map! Rarely seen such an impressive gap!
I agree with all the comments on this map. Everything has been said very well!
I had an RTX 3090 and as my teenagers wanted a new machine, we made a deal :-)
Honestly, the gap between 3090 and 4090 is really impressive! I took this cable https://www.digitec.ch/fr/s1/product/corsair-cable-premium-individually-sleeved-124pin-pcie-gen-5-12vhpwr-600w-type-4-white-cables-dalime-23494431 because I can't connect 4 cables to my power supply ;-) The cable is perfect.
The negative points are rather light and subjective, but I still find that prices are being pushed to dangerous levels! OK I paid the same price for my RTX 3090 as my 4090 but still! What a shame! The rage, bought this Monday morning and already 100.- less on Tuesday noon... That's the game I guess !
In any case, whatever your needs (game, rendering, calculation, etc...) => pffff the monumental slap. It's been a long time since I've been so surprised by such a difference.
As for the noise, it's non-existent (really and without third party software), 0 coil whine (I didn't exceed 220 fps but 0 noise). Everything went perfectly during the installation. No reason to say so, but it seemed to me to be very successful.
Coming from the same brand for my 3090, I was skeptical because the bios was average and it was really noisy despite a very aggressive setting of the fans.
I recommend the use of "Fan control" because it is really magic for all your fans. Works great with the 4090.
For those who are interested, undervolt can be done easily with Afterburner (I did something light). The performance remains the same (1-2% drop) but the power consumption is really reduced! 450-460w => 250-350 depending on the task.
So, a bit of a rambling message but a success for Nvidia and KFA :-)Pro
- performance!
- Silence!
- No coil whine
- Hum prices down
- everything else
- consumption after undervolting! (100-150w gain for 1-2% drop in performance)
Contra
- price (still too expensive!)
- power supply required (small detail)
- Connections (connection supplied = a joke)
- These are really details
- conso (without undervolt)
Super quality & performance incl. good cooling and great RGB optics with ARGB sync
This graphics card is expensive, but unlike a 4070/80, it effectively delivers much more. Performance and cooling are top, even with demanding gaming performance on a 34" 3440x1440 UWQHD, the card is far from the limit (max 50-60 degrees warm, not under load). I use it together with i9-13900K, Asus Z790-E, be quiet! AIO CPU cooling in a Base 500 FX RGB case with ARGB hub, which also allows the 4090 to sync its RGB (see picture).
Applications such as MSFS 2020 are pure pleasure with it.Pro
- Quality & Performance
- 24 GB graphics memory for large screens and high resolutions
- Good cooling capacity
- Great RGB optics
- ARGB Sync possible with ARGB input cable
- RGB support prop included
Contra
- Heavy and large, only have 2-3cm reserve in the housing
- 12VHPWR connection controversial, but works flawlessly for me so far
- Requires 4 PCI-E power cables from the PSU and needs sufficient PSU power
Pure power
My current configuration:
Mainboard: Gigabyte X58A-UD7 (2011, no support since...forever), PCI-E 2.0.
Case by Silverstone, E-ATX.
Yesaaaa.... an old case from 2010 with a Graka GTX 970 from 2015 😊
In parallel, I replaced my power supply from that year and replaced it with a new one with 12VHPWR.
Delivery of the 4090:
The delivery was very fast, top. But....
If I order a product with this value, it should be packed accordingly. Here, the address label was applied to the original packaging(!) by means of an adhesive label, so that everyone could see which product it was. If I now follow the post ticker, it's impressive that the parcel went right across Switzerland and still arrived with me.
By the way: In the same week, a neighbour's delivery of clothes was stolen from the post office.
In contrast, when a replacement fan worth CHF 30 is delivered, elaborate packaging is used (including the flips-dings). There is potential for improvement here. Therefore -1 star, we want to get better :-)
Unpacking and installation:
Neatly packed, extensive cables.
The graphics card is larger than my old GTX 670. The installation went without a hitch, just bear in mind that the graphics card takes up space on 3 PCIEs.
Operation:
Tested with Far Cry 6. The graka always stays cool and now e.g. FC6 is no longer a problem with optimising VRAM. The 24GB VRAM is used with the highest setting with a maximum of half of the VRAM.
This graphics card is simply fun, in every respect. It simply has pure power:
Next step: upgrade mainboard with AM5 socket. I'm curious 😊
Power without end... and efficient
It has exceeded my expectations by far :) I was very sceptical about what I was buying... especially about the price and the coil beeping.
As soon as I unpacked it, I was simply overwhelmed. Beautifully finished, top packaging and accessories. Even with additional fan for baking plate, which is not necessary at temperatures around 55-65 degrees.
The original adapter for the power plug is not a solution for me. I am still looking for an improvement. But all 40 graphics cards have this problem
The old graphics card (3070Ti or 2070TI) had drawn much more power for significantly less FPS.
It is not only a performance monster but also efficient. Haven't even undervolted it. Although this will lead to even better performance (FPS/power consumption).
Under full load, minimal coil whine but only at Full HD (FPS beyond 680..), on WQHD (AVG 460 FPS) nothing audible. Tested with FurMark
Preference also over an AMD because of IDL consumption under 30W, mostly even under 20W. And this with two monitors.Pro
- Nobly processed
- FPS in terms of consumption Top
- Quiet even under full load
- Max Temp with air cooling of 65 degrees
- No coil whine
- IDL consumption under 30W with 2 monitors
Contra
- Adapter power plug
