NVIDIA GeForce RTX 4080 Reportedly Features 16 GB & 12 GB Flavors, RTX 4090 PCB Details Revealed

New particulars of NVIDIA’s GeForce RTX 4090 & RTX 4080 graphics playing cards have been revealed relating to the PCB and reminiscence capacities.

NVIDIA GeForce RTX 4080 Reportedly Features Two PCB Designs With 16 & 12 GB Capacities, RTX 4090 Gets 14-Layer PCB

According to data by MEGAsizeGPU, the NVIDIA GeForce RTX 4090 will are available one PCB taste whereas the RTX 4080 will are available two flavors. The RTX 4090 might be utilizing the identical PCB for reference and AIC designs which might be geared up with as much as 24 GB of GDDR6X reminiscence and 14 layers for the PCB in whole. The NVIDIA GeForce RTX 4080 has already leaked out which you’ll learn extra about right here.

The NVIDIA GeForce RTX 4080, alternatively, is reportedly going to have two completely completely different PCB designs. The first one is claimed to characteristic as much as 16 GB GDDR6X reminiscence capacities and a 12-layer design for AIC playing cards whereas the second mannequin goes to characteristic 12 GB GDDR6X reminiscence assist & a 10-layer PCB design for each AIC and reference fashions.

Now now we have been listening to studies of 16 GB reminiscence being the official mannequin and nothing a few 12 GB variant however NVIDIA did have two RTX 3080 fashions, one with 10 GB and the opposite with 12 GB, launched beforehand. The RTX 3080 12 GB includes a 384-bit bus whereas the RTX 3080 featured a 320-bit bus.

Since the RTX 4080 is rumored to characteristic a 256-bit bus for the 16 GB variant, the 12 GB AIC mannequin will characteristic a cut-down 192-bit bus interface which is a major discount and surprisingly low bus width for a flagship graphics card. NVIDIA must compensate for the GPU bandwidth by upping the reminiscence clocks and introducing a brand new reminiscence compression know-how to make up for its misplaced bandwidth. Maybe that is why the RTX 4080 was lately rumored to have acquired a 23 Gbps GDDR6X reminiscence bump.

It could be no shock to us if the 16/12 GB fashions could possibly be nothing greater than engineering samples as now we have seen 16 GB and 20 GB RTX 3080 fashions within the wild. These graphics playing cards had been certainly made and produced by NVIDIA however weren’t possible for a retail launch.

NVIDIA GeForce RTX 4080 ‘Expected’ Specifications

The NVIDIA GeForce RTX 4080 is anticipated to make the most of a cut-down AD103-300 GPU configuration with 9,728 cores or 76 SMs enabled of the overall 84 models whereas the earlier configuration supplied 80 SMs or 10,240 cores. While the total GPU comes filled with 64 MB of L2 cache and as much as 224 ROPs, the RTX 4080 may find yourself with 48 MB of L2 cache and decrease ROPs too because of its cut-down design. The card is anticipated to be based mostly on the PG136/139-SKU360 PCB.

As for reminiscence specs, the GeForce RTX 4080 is anticipated to rock 16 GB GDDR6X capacities which might be stated to be adjusted at 23 Gbps speeds throughout a 256-bit bus interface. This will present as much as 736 GB/s of bandwidth. This continues to be a tad bit slower than the 760 GB/s bandwidth supplied by the RTX 3080 because it comes with a 320-bit interface however a lowly 10 GB capability. To compensate for the decrease bandwidth, NVIDIA could possibly be integrating a next-gen reminiscence compression suite to make up for the 256-bit interface.

For energy, the TBP is now set to be rated at 340W, a 20W enhance from the earlier 320W spec that we acquired. This brings the TBP to the identical ballpark as the prevailing RTX 3080 graphics card (as much as 350W). Now it’s not recognized whether or not the opposite RTX 40 collection graphics playing cards may also be getting the quicker GDDR6X reminiscence therapy however we all know that Micron has commenced full mass manufacturing of as much as 24 Gbps GDDR6X reminiscence modules in order that they need to go someplace.

• NVIDIA GeForce RTX 4080 “Expected” TBP – 340W
• NVIDIA GeForce RTX 3080 “Official” TBP – 350W

NVIDIA GeForce RTX 4080 Series Preliminary Specs:

NVIDIA GeForce RTX 4090 ‘Expected’ Specifications

The NVIDIA GeForce RTX 4090 will use 128 SMs of the 144 SMs for a complete of 16,384 CUDA cores. The GPU will come filled with 96 MB of L2 cache and a complete of 384 ROPs which is just insane. The clock speeds are usually not confirmed but however contemplating that the TSMC 4N course of is getting used, we predict clocks between the two.0-3.0 GHz vary.

As for reminiscence specs, the GeForce RTX 4090 is anticipated to rock 24 GB GDDR6X capacities that might be clocked at 21 Gbps speeds throughout a 384-bit bus interface. This will present as much as 1 TB/s of bandwidth. This is identical bandwidth as the prevailing RTX 3090 Ti graphics card and so far as the ability consumption is anxious, the TBP is claimed to be rated at 450W which signifies that TGP might find yourself decrease than that. The card might be powered by a single 16-pin connector which delivers as much as 600W of energy. It is probably going that we might get 500W+ customized designs as we noticed with the RTX 3090 Ti.

As for its characteristic set, the NVIDIA GeForce RTX 4090 and RTX 4080 graphics playing cards will rock all the trendy NV characteristic units resembling the most recent 4th Gen Tensor Cores, third gen RT cores, the most recent NVENC Encoder, and NVCDEC Decoder, and assist for the most recent APIs. They will pack all the trendy RTX options resembling DLSS, Reflex, Broadcast, Resizable-BAR, Freestyle, Ansel, Highlights, Shadowplay, and G-SYNC assist too.

• NVIDIA GeForce RTX 4090 “Expected” TBP – 450W
• NVIDIA GeForce RTX 3090 “Official” TBP – 350W

NVIDIA GeForce RTX 4090 Ti & RTX 4090 ‘Preliminary’ Specs:

The NVIDIA GeForce RTX 4080 and RTX 4070 graphics playing cards might be amongst the primary graphics playing cards in addition to the RTX 4090 to launch to players nevertheless we will not inform whether or not the green staff plans to launch them inside this 12 months quickly after RTX 4090 or wait until early subsequent 12 months. The RTX 4090 is thus far anticipated to launch round October 2022.
