Middle-range RDNA 3 graphics cards such as AMD’s Radeon RX 7600 XT seem to utilize the Navi 33 GPU, as @ Kepler_L2 tweeted.

AMD Radeon RX 7600 XT is rumored to adopt RDNA 3 “Navi 33” GPU, aiming for $ 400 segment with faster performance than 6900 XT

The AMD RDNA 3 “Navi 33” GPU, which was previously rumored to be used in the Radeon RX 7700 series lineup, will be replaced by the Radeon RX 7600 series, which is closer to the middle range lineup, in a new rumor by @ Kepler_L2. It seems that it is said.

The current Navi 23 card makes sense as it’s also included in the Radeon RX 6600 series lineup, but that generally means a big jump across the segment.

N33 will be used in the 7600XT, not 7700XT.

We will see 7600XT at $400 or less and 4070 at $500 or less. It’s fine????

The Navi 33 GPU, which is based on the RDNA 3 architecture, is considered a midrange chip and is an optimized version of the Navi 21 GPU with the newer RDNA 3 architecture.

Based on TSMC’s 6nm monolithic design, it is expected to be 360-460mm2 in size.

This means a reduction in die area of 11-30% compared to the Navi 21 GPU with a die size of 520mm2, which drives the high-end Radeon RX 6000 lineup.

The main features of the Navi 33 GPU will be as follows.
TSMC 6nm process node (monolithic GPU design)
RDNA 3 graphic score (clock count / efficiency improvement)
8GB GDDR6 memory optimized for 128-bit bus
GDDR6 memory speed acceleration
Rasterization performance equal to or better than RX 6900 XT
Ray tracing performance superior to RX 6900 XT

AMD RDNA 3 Navi 33 GPU for Radeon RX 7600 series

AMD Navi 33 GPUs will launch a monolithic segment within the RDNA 3 family. This GPU adopts a single die. The die is very similar to the flagship Navi 21 GPU and is expected to utilize 6nm process nodes for manufacturing.

AMD Navi 33 GPU “rumored” architectural design

The Navi 33 GCD is equipped with two Shader Engines, and each Shader Engine is expected to have two Shader Arrays (2 per SE / 4 in total).

Each Shader Array consists of 8 WGPs (8 per SE / 16 total), and each WGP is equipped with 8 SIMD32 units (64 SIMD32 per SA / 128 per SE) with 32 ALUs. It was expected from before.

These SIMD 32 units combine to form 4096 cores, which is the same number of cores as the RX 6900 XT (Navi 21 XTX GPU).

This is a 20% reduction in core count compared to the full fat Navi 21 GPU.

The Navi 33 will basically replace the Navi 23 in the GFX 11 “GFX 1101” architecture, and it turns out that the Navi 23 has only half the 2048 cores that the Navi 33 is supposed to have.

Since the Navi 23 GPU is installed in the Radeon RX 6600 series card, it is presumed that the Navi 33 will be installed in AMD’s RX 7600 series.

Regarding memory configuration, 128-bit bus interface and 8GB VRAM are said to be enough cards for 1080p gamers, but considering that the top chip Navi 31 offers a 384-bit bus, AMD uses 12GB of VRAM across the 192-bit bus interface, and the Navi 32 is likely to have 16GB of VRAM on the 256-bit bus.

The Navi 33 (RDNA 3) GPU on the AMD Radeon RX 7600 series graphics cards is expected to have a 128MB Infinity Cache, but may not be MCD-processed like the Navi 31 and Navi 32 products.

As a result, the performance of the AMD Radeon RX 7600 series will exceed the RX 6800 series and RX 6900 series with a TDP of around 200W (180 to 230W).

It’s also said that the PCIe interface is Gen 5.0 along with the x8 link, but don’t worry, the Gen4 and Gen3 x8 links can provide enough bandwidth to the card.

Efficiency will be AMD’s RDNA 3 really powerful suite, and the red team is likely to lead NVIDIA’s GeForce RTX 40 “Ada Lovelace” lineup, which is expected to consume very much power.

AMD Navi 33 GPU Features, Price, Performance “Rumors”:

In terms of performance, the AMD Radeon RX 7600 XT, which is based on the Navi 33 GPU, can be expected to perform better than the 6900 XT class in ray tracing, but given the memory-reduced design, it will be hit as the resolution increases. Become.

Therefore, it will be faster at around 1080p and about the same at 1440p, but at 4K and above it will eventually be the same or slower due to the limitation of 8GB VRAM.

Ray tracing is expected to be a strong point as this card offers higher performance than the RX6900 XT.

8GB may sound like a downgrade to the RX6900 XT, but given the price, it’s great not only to save money, but also to mass-produce cards without worrying about the supply of GDDR6. It may be a decision.

The AMD Radeon RX 7600 XT graphics card is expected to be priced below $ 400, which is similar to the RX 6600 series, given the 6700 XT’s suggested retail price of $ 379.

Cut-down models can also cost less than $ 350.

If the rumors are true, you can get the performance of the RX6900 XT for less than half the price and it should be a hot seller in the middle range segment.

Explanation:

Information on the middle range RX7600XT of RDNA3

In terms of performance, it is said that RX7600XT = RX6900XT.

This is a performance jump higher than Ada Lovelace, and I think that the middle range is higher in performance and cost performance in RDA3.

Initially it was thought that the RX7600XT would be a rename or shrink of the RX6900XT, but since the GPU architecture of RDNA3 will change, it seems that it will simply be the same number of SPs.

Since this is $ 400, it is a cost performance of the current RTX 3070 or higher. (However, if the yen does not depreciate in the future)

In the RTX4000 series, only AD102 has a large number of CUDA cores, and the GPU chip after that is not so much, so performance may be sluggish for models other than high-end models, and only the top model can beat RDNA3, less than that. I think that the model of is likely to be defeated by RDNA3.

However, the RTX4000 series also has a large-capacity cache that is very similar to the Infinity cache, and there is no possibility that it will be extremely efficient because the game performance is high for the FP32 computing performance like RDNA2. There is no such thing as this area until the actual game performance leaks.
