AMD Readies Radeon RX 7400 and RX 7300 Based on "Navi 33" Silicon
AMD is rumored to be readying two new entry-level desktop GPU models in the Radeon RX 7000 series. These are the RX 7400 and the RX 7300, which probably succeed the RX 6500 XT and RX 6400, respectively. Perhaps the most interesting aspect of the two are the silicon they're based on. Apparently, AMD is carving the two out from its 6 nm "Navi 33," the same chip it uses for its Radeon RX 7600 and RX 7600 XT SKUs.
The "Navi 33" monolithic silicon is based on the RDNA 3 graphics architecture, and has 16 workgroup processors (WGPs), or 32 compute units (CU), worth 2,048 stream processors, 64 AI accelerators, 32 Ray accelerators, 128 TMUs, and 64 ROPs. The silicon is maxed out in the RX 7600 and RX 7600 XT, and we haven't seen anything to suggest the existence of a desktop RX 7500, which means the RX 7400 and RX 7300 could be heavily cut down from the chip, with AMD reducing not just the CU count, but even the 128-bit GDDR6 memory bus width.

Even if 7400 and 7300 use only 1024 and 768 stream processors, I expect that they wouldn't be limited to 4 PCIe lanes, as the 6000 series.
Details:
I used a NVIDIA 960 GTX 4GB in 2023 for at least two months as main graphic card. (I was interested in the NVIDIA driver quality in 2023. I was interested in the performance in the lower end. Card can not be used for anything. For GNU Linux you want a Radeon. Windows operating system takes much longer to boot as the nvidia gpu with the older and newer vbios initializes the screen twice which costs around 5 seconds at least. Driver did not improve with the 600 Nvidia series. A lot of issues with the linux kernel in gnu linux. A hassle to use a Nvidia card basically in gnu linux)
I used the Ryzen 7600X processor graphics with lots of VRAM in 2023. (good for desktop use - struggles with basically anything)
I build my box on purpose with 64GiB RAM. So I had spare for the processor graphics when needed. I believe the processor graphic is sufficient for windows 11 pro and gnu linux desktop tasks.
I used for around two years a RADEON 6600 XT. (I bought it fresh - was a decent card for gaming as the mining boom was going on)
I had for a few months the Radeon 6800 non XT. (I bought a MSI Card which had some hardware flaws with the fan curve and the fan design - bad luck - bad windows and gnu linux driver - clock issues and therefore high power draw issue)
For quite a while I have the Powercolor Radeon 7800XT hellhound - basically an entry gaming card for WHQD.
A tiny bit off topic, but I dont understand why AMD and Nvidia dont "just" use mobile gpus in the lower end desktop gpu segment? To me that seems like a no-brainer.
Guttural reactions aside, I could look forward to the 7300 being a prospective display adapter to further bury the dusty ass GT1030 and add some spicy competition to the Arc A310. The 7400 might do okay as a slap-in card for SFF office PCs or for uber-tiny emulation boxes if they manage to spec it with 96-bit/6GB or somesuch.
So, that "no-brainer" as you called it, must come from Nvidia. Only then tech press and users will praise it.
And Nvidia will never do it. Nvidia needs to move prices higher for better profit margins because iGPUs are becoming relatively too strong covering the needs of most consumers. Nvidia mobile GPUs covering the sub $150 market are a very difficult puzzle. If they are too weak consumers will not be happy. If they are good products, consumers might lose interest for cards like the 4060.
When being used with older (e.g. PCIe v3) chipsets, 8x vs 4x would help a bit, especially as these cards would likely have not huge amounts of VRAM. Unlikely to see PCIe 3 systems you say?? Well, lets not forget AMD are still promoting AM4 and low-end gimped Cezanne/Renoir dies with no working iGPU will still only have PCIe v3 capability.

Those are the best selling GPUs on Amazon.ca and Newegg.com it shows that budget is still viable but the 3060 is still a very popular card. Probably why Nvidia does not want to really change that. It is not that the 6600 is not a good GPU but the data does show that the price/performance of the 6750XT is real and there are no 4090s in there for at least 25 positions.
If this 7400 can give us even a 6GB frame buffer it will be better received and you know AMD are not going to leave AV1 support out, even though it was a nothing burger. Anything more than that would threaten the 6600/7600. If they are priced right AMD can use it's software stack to make it shine at 1080P with all of those dials they have.
Let's say $199 CAD or about $149 US.
I hope I'm wrong.
I was very close in getting a 3060, but the timing didn't worked. I bought an RX 6600 at 180 euros, a price that was looking great when I bought it and wasn't expecting it to go any lower. One month after I bought the RX 6600, the biggest retailer in Greece put on sale the 12GB RTX 3060 at 220 euros. Damn, if I haven't bought the RX 6600 I would have bought the 3060 instantly. 12GBs with acceptable performance for 220 euros THIS period? It's a steal.
There's an interesting performance and price point that has to be struck in the lower end market and it breaks down to a few categories:
LIGHT gaming, as in the OLD OLD game server types of systems that are producing a picture and rendering the game in real time
Professional/Security situations where you need to output to several displays at any framerate, basically a multiscreen H.264 render
Low cost provision for SFF PCs or servers that need a picture device for specific tasks that prove absolutely insufferable without acceleration. Nope, too expensive at any price point. Yeah no, I'm immediately suspicious of this one. When is the last time you guys have actually looked at an RX 6400 seriously?
Single HDMI and DP. Does not look like a very capable card and it's probably how my full size RX 580 should have shipped.
You just know first glance that nobody is seriously putting that thing to work.
It's a junk class (minimum performance) accelerator with one of each modern display out for sake of compatibility. That's it.
I've considered it for my rack when the A380 looked like a broken promise and I would have made the jump to it except...
There it is. So what can we expect from the RX 7400 if these are the issues for the previous gen+class?
It's not an encoder card which means OBS is out.
It's not going to play well with most games at 1080p unless LOW settings.
There may be driver related issues just getting certain antique apps to behave.
It's not something you pick up for mission critical work. It's a last resort option for getting a picture without the stank of a GT1030.
I wouldn't want this in a laptop either.
