youtube algorithm recommended this to me on the home page, never seen a channel with less than 1 thousand subs get that before.

I have always wondered by AMD hadn't leveraged the fact that they make both CPU's and GPU's to make them both work better when paired to together and now I have my answers.

Pumping out more and more content to catch the wave... I respect the hustle

AMD is implementing a shared memory system for GPU/CPU on the new XBOX and PlayStation consoles which will probably lead to smarter memory management from developers trying to squeeze as much performance as they can out of the hardware. This could bode well for optimization leaning in AMD's favor with this "SAM" technology.

Gotta say, YouTube's algorithm is getting very smart. You popped on my front page yesterday with your last video and now I'm officially impressed. Great video and sound quality, great scene and vibe and helpful and important info. You're gonna go far man keep that grind up. Cheers from Argentina 😸👍

Wow man! Look at you go. I just subbed like a week ago and you’ve already passed me. Keep putting out those quality videos. Great news information

Here I am at 900 subs thanks to youtube recommendation. Hope all is well at school for obvious c-reasons. I like that you do videos on something you like. I wish I can start doing that someday. I still need the hardware to start, but I still have the wish.
have a nice week

Games that are console ports would likely see a large benefit, for instance Horizon Zero Dawn a game written for PS4 with unified memory is known to heavily abuse the PCIe bus on PC. This may not be the case for every console game, but many console games use the unified memory to directly push animation and geometry updates at extreme rates compared to most PC titles (since its literally just a memory copy). I would bet that Forza Horizon 4 is mainly written as an Xbox game that happens to also run on PC.

SAM is going to be a big reason to upgrade almost every part of your pc

I’m really impressed, I saw this and was like who is this guy I’ve never seen him before, and realized no one had and then subscribed immediately!

[TheRekkr]

I saw this video and realized my man only had 703 subscribers so I HAD to subscribe. Your content is crazy good, keep up the hard work. You’re going to blow up.

Wow, I am glad your video was in my feed this morning. Great video, and well spoken at an easy going pace thats easy to follow. Needless to say, I am a new sub. Im looking forward to more content from you!

Win10 was changed recently to support the extended BAR used by SAM, Linux had the capability already. This may be fruit from Sony/MS console collaboration, where there's a shared address space
Enabling it is a BIOS option.

Some comments elsewhere assume an existing BIOS option ">4GB MMIOs" is the same, but that looks like a 32bit vs 64bit compatability option to me
Intel may have screwed the pooch up by not fully adopting AMD64 architecture 15 years ago, which included DMA access to the full 64bit address space without bounce buffers (in 32bit memory).
SAM may require Intel to implement 64bit better in CPU and chipset to work; technical debt with a vengeance!!
(Edit: fix typo 4GB not GM )

First public post in youtube here, thanks for your videos Daniel, its nice to see someone making tech videos that also has a day job. The topics you cover are things that I'm wondering about as a consumer and it helps that you've went to gather the information to share it with us in your videos and I do not need to go digging about to make the comparisons and formulate the thoughts and answers. I also enjoy the video and sound quality (I like videos where the breathy words do not go into the mic as it creates alot of bass booms with my bass heavy setup lol). Keep this up and all the best.

[Sneedoss]

Well done mate. About 4x more subs I last saw you. Epic!

[Glen_]

Love the content, I’ve actually been playing with the idea of starting my own channel. But honestly wasn’t sure it would go any where or if anyone would ever watch lol. But your channel has convinced me that I should just go for it and see what happens, so thanks

[wolfysp]

Keep up the good work m8, it's good to get all info from various Techtubers and your channel is going well 👍😁

[unearth]

Shocked you don't have more subs. Great content!

[oscarbecker]

As I mentioned in other videos comments before, I am pretty sure that SAM will benefit huge (in some newer games) from core count. I really would love to see results of all tree cards coupled with a R9-5950 an SAM turned on!

Excellent content! I first saw your Game Pass video and subbed then. Glad that you're releasing content frequently.
