Bitspower today introduced the Nebula VGA full-coverage water-block for the AMD Radeon RX 7900 XTX reference-design graphics card (model: BP-VG7900XTXRD). The block uses nickel-plated copper as its main material, and comes with a clear-acrylic top that's studded with addressable-RGB LEDs. It also includes a metal backplate. The block features a mirror-finish contact area for the GPU, and comes with thermal-pads for the card's twelve GDDR6 memory chips, and its VRM areas. The lighting setup takes in a common 3-pin ARGB connection. The block itself comes with industry-standard G1/4" threads for fittings. The block measures 270 mm x135.5 mm x 30.7 mm. Up for pre-order, the Nebula RX 7900 XTX FC-block is priced at the equivalent of USD $250.

It would seem that all the blocks for the 7000 series are all the same design. A reservoir sitting on top of the block. It even has the same ribs as my Alphacool unit and I assume the ribbed area is for the I/O die.

Ribbed area? You mean the fins over the GPU die present on every waterblock ever? :confused:

I'm more curious about the backplate. If the backplate has thermal pads where the VRAM is, the increase in surface area could potentially help as opposed to the completely flat backplates everywhere? If it's not a purely stylistic choice.

On my Alphacool unit it came with Pads for the rear of the memory and Chip but also VRAM. The one I meant is the ribbed on over the die as the chips surround the die from what I can see.

What do you mean? The fins are contiguous.........it's just that they chose a jet plate that isn't transparent so it covers part of it. The finned area is as least as big as the contact area.

Having had a few Bitspower blocks, I can't really complain about them. I have not paid more than $150 for any of their blocks from my local Microcenter. They have come with extra thermal pads in the past and I typically put those on the back side so the backplate can soak some heat.

Though pre-applied pads would be new.

If you look at the Image you will see what I am talking about. The top block is for a 7000 series GPU and the one below is from a 6800XT. There is way more volume for the GPU and the orientation is vertical instead of horizontal. The Channels are defined on the 6800XT block but not so on the 7900.

Hi,
Yeah the design of the 70 series/ green fluid looks like it's going to have poor flow on the one side proved by the air bubble in it lol
Lower copper block has better flow design but looking pretty bad must not of stored it very well my 5 year old ek titanXp copper block still looks new.

If you notice there is a washer inside the block that is the source of all of the "dirt" in the loop. EK's quality has definitely gone down. I also had another one sprout a gasket "Also for a 6800XT" that actually looked interesting with RGB lighting. Needless to say Alphacool and Byiski are my go to but mostly Alphacool as they have much better shipping. If I want to wait the 2 + weeks I usually order Alphacool stuff from Groovesland as they offer free World wide shipping. I ordered a DDC pump that cost me $60 Euros and $3 for tracking on my package. The Exact same pump is on Amazon for $80 and $60 shipping. I have never used Bitspower but to me it looks like all of these blocks have the exact same design for the 40 series and 7000 series cards.
