AMD

Other than framework (out of stock) does anyone know of a good linux gaming laptop with a dedicated AMD GPU? (equivalent to 3060 or more) that I can buy in the UK?

any help would be appreciated- these seem to be rare.

There were some leaks, suggesting either:

• Strix Point for AM5 with higher TDP
• Two chiplets - (8 x Zen5 CPU + RDNA 3.5 *16CU)

I never expected that AMD would leave this segment with old chips, especially given Intel's solid iGPU performance.

So, are desktop APUs to come out this year and if so, what is coming ?
Has anyone heard anything more ? 🙄

Hi guys, how y'all doin? I was thinking about building a new work/gaming PC in the near future and thought to myself I would go full AMD. Just wanted to ask if there are any modern motherboards in 2025 which support disabling or atleast turning of parts of AMD PSP?

Thx in advance.

At least 8700G has AI cores in the cpu. Is it possible to shutdown them in bios? Also, does those cores work in Linux at all?

It seems that the latest AMD Adrenaline drivers for Windows require that you agree to AMD's AI Acceptable Use Policy.

This was not present on the 25.2.1 optional drivers, but is required on the 25.3.1 drivers in order to complete the installation.

While I wait on 3rd party reviews I'm mulling over whether or not to swap out my 6950xt for the 9070xt.

My current card is fine for me in 1440p ultrawide, though it does get hot and is (for me) noisy.

The main consideration is (tethered) VR gaming. The 6950xt is ok but it feels like it's just short of where I want it, but I'm not sure how much of a difference there'd be between the 2 cards.

Yesterday Framework unveiled a small form factor desktop based on Halo Strix.

Halo strix seems to require memory with high bandwidth, specifically 256-bit LPDDR5x, according to the specs.

Allegedly, the company said they tried to find a solution to use modular memory (e.g. lpcamm) but it did not work out signal integrity wise (@36:10, from the unveiling video above and here.)

So I'm wondering exactly, why not?

It seems LPCAMM2, offers a 128-bits bus and can scale today up to 7500-8500 MT/s.

This would offer 7500 x 128 / 8 = 120GB/s. Would it not have been possible to simply place two LPCAMM2 modules, to cover the full extent of the 256-bit bus and reach the 256 GB/s, by using the 8000 MT/s configuration?

Did they reach integrity issues because they tried to reach the speeds using only one LPCAMM2 stick? That would indeed have been impossible. Maybe LPCAMM2 can not be combined (perhaps due to space as they are using the mini-ITX motherboard format)? Or am I missing something?

Ahead of tomorrow's availability of the AMD Ryzen 7 9800X3D processor as the first Zen 5 CPU released with 3D V-Cache, today the review embargo lifts. Here is a look at how this 8-core / 16-thread Zen 5 CPU with 64MB of 3D V-Cache is performing under Ubuntu Linux compared to a variety of other Intel Core and AMD Ryzen desktop processors.

The AMD Ryzen 7 9800X3D as previously shared is AMD's first processor leveraging 2nd Gen 3D V-Cache. The 64MB of cache is now underneath the processor cores so that the CCD is positioned closer to the heatsink/cooler to help with more efficient cooling compared to earlier X3D models.

The AMD Ryzen 7 9800X3D boosts up to 5.2GHz and feature a 4.7GHz base clock while total it provides 104MB of cache. Like with the prior 8-core Ryzen 7 7800X3D, all eight cores have access to the 64MB 3D V-Cache. The Ryzen 7 9800X3D features a 120 Watt default TDP. AMD's suggested pricing on the Ryzen 7 9800X3D is $479 USD.

The AMD Ryzen 7 9800X3D will work with existing AMD AM5 motherboards with a simple BIOS update. For my testing I was able to use the ASUS ROG STRIX X670E-E GAMING WIFI motherboard previously used for all Ryzen 9000 series testing after a simple BIOS update. AMD also sent out an ASRock X870E Taichi motherboard as part of the review kit. For these 9800X3D benchmarks I ended up testing both initially on the ASUS ROG STRIX X670E-E GAMING WIFI motherboard to match the previously tested Ryzen 9000 series processors and then repeated the run with the ASRock X870E Taichi motherboard as well for reference.

Given the information around how AMD are currently focusing on the mid tier, it got me thinking about their focus on multi chiplet approaches for RDNA5+, they will be having to do a lot of work to manage high speed interconnects and some form of internal scheduler/balancer for the chipets to split out the work etc.

So with this in mind if they could leverage that work on interconnectors and schedulers at a higher level to be a more cohesive form of Crossfire/SLI they wouldnt even need to release any high end cards, as they could just sell you multiple mid tier cards and you just daisy chain them together (within reason). It would allow them to sell multiple cards to individuals increasing sales numbers and also let them focus on less models so simpler/cheaper production costs.

Historically I think the issues with Crossfire/SLI was that to make best use of it the developers had to do a lot of legwork to spread out loads etc, but if they could somehow handle this at the lower levels like they do with the chiplets then maybe it could be abstracted away from the developers somewhat, i.e you designate a master/slave GPUs so the OS just treats the main one as a bigger one or something.

I doubt this is on the cards but it felt like something the was plausible and worth discussion.

Thanks to Valve's Linux graphics team, VK_EXT_device_generated_commands is now supported by the Radeon "RADV" Vulkan driver with the upcoming Mesa 24.3 release.

Prominent RADV developer Samuel Pitoiset at Valve has landed support for VK_EXT_device_generated_commands, the multi-vendor device generated commands "DGC" implementation. Last month with Vulkan 1.3.296 the VK_EXT_device_generated_commands extension was introduced to succeed NVIDIA's vendor-prefixed DGC extension. The device generated commands extension allows for the GPU device to generate a number of commands for command buffers. VK_EXT_device_generated_commands is a very big and important addition to the Vulkan API: Valve's Mike Blumenkrantz has argued that DGC is the biggest addition to Vulkan since ray-tracing.

AMD has been teasing the Ryzen 9000X3D Zen 5 CPUs with 3D V-Cache and today they formally announced the specs of the Ryzen 7 9800X3D processor that will begin shipping 7 November.

The AMD Ryzen 7 9800X3D is AMD's 8-core / 16-thread processor with 64MB of 3D V-Cache. This uses 2nd Gen AMD 3D V-Cache where the 64MB of cache is now underneath the processor cores so that the CCD is positioned closer to the heatsink/cooler. The intent is that the new 3D V-Cache processors will run cooler than prior generation 3D V-Cache processors.

The AMD Ryzen 7 9800X3D will boost up to 5.2GHz and feature a 4.7GHz while total it provides 104MB of cache. This 120 Watt processor will have a suggested retail price of $479 USD. Again, expect retail availability on 7 November.

This community seems to be abandoned by the moderator, but people are still keeping it alive, I would like to offer an alternative one for those people. Fair or unfair lemmy.ml has a reputation that limits its potential pool of contributors.

The AMD Ryzen 9000 series starting with the Ryzen 5 9600X and Ryzen 7 9700X launching tomorrow are some truly great desktop processors. The generational uplift is very compelling, even in single-threaded Linux workloads shooting ahead of Intel's 14th Gen Core competition, across nearly 400 benchmarks these new Zen 5 desktop CPUs impress, and these new Zen 5 desktop processors are priced competitively. I was already loving the Ryzen 7000 series performance on Linux with its AVX-512 implementation and performing so well across hundreds of different Linux workloads but now with the AMD Ryzen 9000 series, AMD is hitting it out of the ball park. That paired with the issues Intel is currently experiencing for the Intel Core 13th/14th Gen CPUs and the ~400 benchmark results makes this a home run for AMD on the desktop side with only some minor Linux caveats.
