- trympet 3y agoIs that directly relevant to the consumer? The M1 architecture seems to be fairly sustainable. Intel, not so much.
- rgrs 3y agoIt is relevant to the benchmarks which are used in ads

- nightski 3y agoIt is, because I can buy a framework laptop w/ 64GB ram, 2 TB SSD and these latest Ryzen chips for half the cost of a macbook pro with similar addons.
- bhj 3y agoThat 64GB RAM isn’t also VRAM though. Not exactly a direct comparison.
- wtallis 3y agoIt is in a Framework or any other low-power system that doesn't use a discrete GPU.

- dragonwriter 3y agoMy understanding is that the only reason dGPUs generally don’t use system RAM isn’t that they don’t have access, but that the supporting software doesn’t use it out of choice because the of the speed hit (iGPUs, of course, do generally use system RAM as VRAM.)
- nordsieck 3y ago> My understanding is that the only reason dGPUs generally don’t use system RAM isn’t that they don’t have access, but that the supporting software doesn’t use it out of choice because the of the speed hit It looks like one of the advantages of Apples put-everything-on-the-package strategy is that they can have a very wide bus to ram, which makes using system ram for the GPU much more palatable.
- amaranth 3y agoIsn't the main difference that Apple is building something like 4-16 channel memory controllers in a mobile device while you normally don't get more than 2-4 channels even on a desktop? That's a lot of transistors and (potentially) power usage but if you can get on the latest node and have a market willing to pay for giant chips it lets you get impressive amounts of bandwidth. I don't think you need the RAM to be on the same package for that, it just makes the timings easier.
- rowanG077 3y agodGPUs do have access to system RAM. It's goes over the PCIe bus and because of that is too slow for direct usage.
- efficax 3y agohalf? not likely
- nightski 3y agoYes, I am not exaggerating. The Framework came to around $1.8k and the Macbook Pro came to ~ $3.9k. The only compromise with the Framework is that it is a 13" screen and the Macbook pro is a 14". But that's because Apple only offers up to 24GB ram on the 13".
- plorkyeran 3y agoThe "Apple tax" isn't really a thing for midrange specs any more, but they will absolutely charge you out the nose to max things out. The top-end macs are targeted at people who won't even notice if the laptop's price is doubled.
- techdragon 3y agoWe notice… but grumble and pay it because we’ve justified it to ourselves. There are of course outliers with heaps of money that don’t care about the cost, but few businesses are so cavalier with cashflow as to not notice and check why someone is buying a $7k laptop or $25k desktop
- goosedragons 3y agoThey charge you out the nose even to do small upgrades. $200 for bumping the SSD from 256GB to 512GB and $200 to go to 16GB RAM. You can easily find brand name good PCIe Gen 4 2TB NVMe drives for less than $200 now.
- olliej 3y agoI think we can’t make claims about “fairly sustainable” until it’s been around for more than two releases.
