tech outlet Angronomics has a really detailed roundup printed relating to the specs of AMD’s RDNA 3 GPUs such because the Navi 31, Navi 32, and Navi 33 chips that can go on to energy their next-gen Radeon RX 7000 collection graphics playing cards.
AMD Navi 31, Navi 32, Navi 33 “RDNA 3” GPUs For Radeon RX 7000 Collection Graphics Playing cards Detailed
Beforehand leaked info inside the Linux patches has revealed that there are going to be no less than 4 RDNA 3 IPs that might be launched for the patron phase. These embody Navi 31, Navi 32, Navi 33, and an APU design referred to as Pink Sardine.

Now Angronomics has reported info such because the sizes, GPU configurations, and options that will find yourself within the closing retail merchandise. An fascinating assertion by the tech outlet has been made which reveals that configurations for Navi 3X GPUs have been first formulated in 2019 after which finalized someday in 2020. These specs haven’t been modified since nonetheless, numerous rumors have identified two completely different specs for the GPUs which implies that both AMD has actually made adjustments since their closing designs or these rumors have been merely not aligned with the reality. With that stated, let’s have a look at what kind of configurations we will count on with the Navi 3x “RDNA 3” GPU lineup.
AMD confirmed that its RDNA 3 GPUs might be coming later this 12 months with an enormous efficiency uplift. The corporate’s Senior Vice President of Engineering, Radeon Applied sciences Group, David Wang, stated that the next-gen GPUs for Radeon RX 7000 collection will provide over 50% efficiency per watt uplift vs the present RDNA 2 GPUs. A few of the key options of the RDNA 3 GPUs highlighted by AMD will embody:
- 5nm course of node
- Superior chiplet packaging
- Rearchitected Compute Unit
- Optimized graphics pipeline
- Subsequent Gen AMD Infinity Cache
- >50% perf/watt vs RDNA 2
Players ought to count on fluid 4K gaming to be buttery clean on these graphics playing cards and with the FidelityFX suite providing next-gen FSR, SAS, and SAM help, we would even see playable 60 FPS at 8K decision.
AMD Navi 31 “Plum Bonito” GPU configuration
The AMD Navi 31 GPU, the flagship RDNA 3 chip, would energy the next-gen fanatic playing cards such because the Radeon RX 7900 XT graphics card. We have now heard that AMD will drop CU (Compute Models) in favor of WGP (Work Group Processors) on its next-gen RDNA 3 GPUs. Every WGP will home twin CU (Compute Models) however with twice the SIMD32 clusters versus simply 2 on every CU inside RDNA 2. Rumors are that AMD has the choice to pick out between Samsung and TSMC for the 6nm die.
- AMD Navi 31: 12288 Cores, 384-bit Bus, 192 MB Infinity Cache, 308mm2 GPU The @5nm
- AMD Navi 21: 5120 cores, 384-bit bus, 128 MB Infinity Cache, 520mm2 GPU The @7nm
In response to the newest info, the AMD Navi 31 GPU with RDNA 3 structure is predicted to supply a single GCD with 48 WGPs, 12 SAs, and 6 SEs. It will give out a complete of 12,288 SPs or stream processors. This is a rise of two.4x in cores in comparison with the 5120 SPs featured on the Navi 21 GPU. The GPU or the Navi 31 GCD is alleged to measure 308mm2 and can come packaged on TSMC’s 5nm course of node.
The Navi 31 GPU may even carry 6 MCD’s which is able to characteristic 16 MB Infinity Cache per die and are additionally more likely to carry the 64-bit (32-bit x 2) reminiscence controllers that can present the chip with a 384-bit bus interface. Whereas this equals 96 MB of Infinity Cache which is decrease than the 128 MB featured on the present Navi 21 GPUs, there’s additionally a 3D-Stacked resolution within the works which was identified not too long ago and that might double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacities for a complete of 192 MB of cache. This can be a 50% improve versus the present Navi 21 design and it additionally makes Navi 31 the primary GPU with each, chiplet and 3D stacked designs. These chiplets or MCD’s might be fabricated on TSMC’s 6nm course of node and measure 37.5mm2 every.
The outlet studies that there was a good greater 288 MB (16 MB 0-Hello + 16 MB 1-Hello + 16 MB 2-Hello) MCD bundle deliberate however that was scrapped because of cost-benefit causes. There are additionally talks of a cut-down variant of the Navi 31 GPU which is able to characteristic 42 WGPs or 10,752 cores and 5 MCDs for 80MB Infinity Cache throughout a 320-bit bus interface.
Now, that is going to lead to greater energy draw and AMD appears to have confirmed this a lot that their next-generation graphics card lineup will characteristic greater energy consumption however they are going to nonetheless be a extra environment friendly possibility than what NVIDIA has to supply. The AMD Radeon RX 6950 XT already has a TBP of 335W so for a >2x efficiency achieve. The playing cards are anticipated to retain their twin 8-pin plug enter for energy and have an up to date triple-fan cooling design which is barely taller than the one presently in use.
AMD Navi 32 “Wheat Nas” GPU Configuration
The AMD Navi 32 GPU codenamed “Wheat Nas” can also be one of many two MCM GPUs featured within the RDNA 3 lineup. The GPU will characteristic a single GCD (Graphics Compute Dies) and 4 MCDs (Multi-Cache Die). The GPU or GCD is alleged to measure 200mm2 whereas every MCD will retain the identical dimension at 37.5mm2.
- AMD Navi 32: 7680 cores, 256-bit bus, 64 MB Infinity Cache, 200mm2 GPU The @5nm
- AMD Navi 22: 2560 Cores, 192-bit Bus, 96 MB Infinity Cache, 335mm2 GPU The @7nm
The GCD might be outfitted with 3 Shader Engines and every Shader Engine has 6 Shader Arrays (18 in complete). The GPU will characteristic a complete of 30 WGP or 60 Compute Models for a complete of 7680 cores. This rounds as much as >50% extra cores than the Navi 31 flagship.
Every MCD must also characteristic 2 reminiscence join hyperlinks (32-bit). That is a complete of 8 32-bit reminiscence controllers for a 256-bit bus interface. Every MCD will retain the 16 MB 0-Hello capability however there doesn’t appear to be any 1-Hello variant which implies that the chip can have simply 64 MB most configs. That Navi 32 GPU is alleged to launch in 2023 and would be the highest chip for cellular and mid-tier chip for desktops. The GPU can be first rolled out to the cellular phase and is perhaps introduced at CES 2023 which makes ultimate sense since we can have Phoenix Vary and Dragon Vary laptops with Zen 4 cores prepared by then.
AMD Navi 32 “Hotpink Bonefish” GPU Configuration
The AMD Navi 33 GPU codenamed “Hotpink Bonefish” will begin the monolithic phase inside the RDNA 3 household. The GPU will characteristic a single die. The die is similar to the flagship Navi 21 GPU and is predicted to make the most of a 6nm course of node for fabrication with a die dimension of 203mm2.
- AMD Navi 33: 4096 cores, 128-bit bus, 32 MB Infinity Cache, 335mm2 GPU The @6nm
- AMD Navi 23: 2048 cores, 128-bit bus, 32 MB Infinity Cache, 237mm2 GPU The @7nm
The Navi 33 GCD is predicted to characteristic 2 Shader Engines and every Shader Engine has 2 Shader Arrays (2 per SE / 4 in complete). This rounds as much as 16 WGP’s or 32 Compute Models for a complete of 4096 cores which is greater than the Radeon RX 6800 “Navi 21 XL” GPU. The GPU will come packaged with 32 MB of Infinity Cache, the identical quantity because the Navi 23 GPU, and throughout a 128-bit large bus. Similar to the Navi 32 GPUs, the Navi 33 chips might be centered first on the cellular lineup with early graphics efficiency placing them forward of the Intel Arc Alchemist lineup at lower than half the price & whereas pulling much less energy.
The outlet additionally talks about two new options coming to AMD RDNA 3 Navi 3x GPUs for Radeon RX 7000 collection graphics playing cards equivalent to:
One of many options within the RDNA 3 graphics pipeline is OREO: Opaque Random Export Order, which is simply one of many many space saving strategies. With gfx10, the pixel shaders run out-of-order, the place the outputs go right into a re-order buffer earlier than shifting to the remainder of the pipeline in-order. With OREO, the following step (mix) can now obtain and execute operations in any order and export to the following stage in-order. Thus, the ROB will be changed with a a lot smaller skid buffer, saving space.
The Reminiscence Connected Final Degree (MALL) Cache blocks are every halved in dimension, doubling the variety of banks for a similar cache quantity. There are additionally adjustments and additions that improve graphics to MALL bandwidth and scale back the penalty of going out to VRAM.
The AMD Radeon RX 7000 “RDNA 3” GPU lineup based mostly on the Nav 3x GPUs is predicted to launch later this 12 months with studies pitting the flagship Navi 31 launch first adopted by Navi 32 and Navi 33 GPUs.
