Wow didn’t see that coming. I met him at a HOPE conference with Steve Wozniak. Followed him for years from hacker zine texts distributed on CDs back in the day. Wow that’s really sad what a fun guy he was. His social engineering book was pretty interesting. That OKI phone story was so fascinating I bought a couple to see if I could do it too, although by then 900MHz was phased out. This guy made a difference in my life how very strange
Not to negate the amazing accomplishments here but, is saved the right word? After all they were saved but only to later die of something else. So prolonged might be more accurate although then you are forced to consider if that’s a good or bad thing. Because if you prolong someone’s life and they have a poor standard of living is it even worthwhile or are you just dragging out their suffering? I mean I see the most successful businessmen in history spending billions on rockets rather than buying mosquito nets to save lives by the dollar and I have to wonder if they haven’t come to the same conclusion. That is; the quality of the experience is as important as the length.
No compare it to the MBA 15 w 512GB SSD and 16GB RAM upgrades and the 70W charger from their educational store + $150 gift card offer. $1575 inc Cali tax
Yes but the AMD design draws double the power even though it was fabbed on a lower process node. I mean it defeats the purpose of a portable. Now you need double the battery weight or lose half the runtime. No, the M2 still wins. If processing is the goal at the expense of portability then you can buy a nice 64 core EPYC system for $1700
The battery life is still fine. Plugging in once in a while isn't a huge deal. I'd rather save time compiling than not having to plug in once every 8 hours.
Yeah I was just referring to default prices. The only one I modified was the comparison to the Overkill system because the base Apple configuration does not have 32GB of RAM and 1TB SSD.
Ok, but that same spec is 1699 plus tax direct from Apple without a discount so the same as frameworks pre built 16 inch option that ships in Q4. If you compare their “build it yourself and bring your own OS” version without memory or storage shipping in late Q4 the base MBA 15 +70W charger w/o discount is still $100 cheaper, shipping now and very likely will outperform w double the battery life
What's the comparison look like with 2TB of storage? And maybe a bit more RAM (I don't think MBAs let you upgrade after purchase so buying a 512GB machine seems shortsighted for a lot of use cases unless all your development is in the cloud)
The storage and memory upgrades are expensive and also have a penalty in terms of power. Memory draws the same current regardless of if it’s being used and that is significant. Unified memory is also very different, has much higher bandwidth than RAM and lower latency. You can’t compare unified memory with RAM.
As far as the SSD, the base option comes with one 256GB NAND flash IC, where if you upgrade to 512GB they have to add a second. That matters because adding a second means you double the IO bandwidth using their current design. It’s something like 3500 vs 7500 MB/s. If you add more NAND modules you also scale up the IO speed further but the difference between 3500 and 7500 is significant for all workloads where above that you probably won’t see a gain except in niche applications like video editing, assuming you have the complimentary processing power and unified memory to utilize that throughput. For storage, Apple provides 2TB cloud service for $10/mo and these have wifi 6E so it’s cheaper to use the cloud than buy the storage, assuming it’s not working storage, and safer too.
Also, upgrades on Apple products hold their market value very poorly. The M2 studio just came out and maxed out M1 units are on sale NIB at 1/4 price of retail from 3 months ago, which is not at all a true quantification of performance since the M2 is only what 15-20% faster.
So after quite some research for the MBA 15; 16GB + 512GB + 70W adapter is the optimum for power draw, performance, cost and value preservation.
Overall, it seems the best value strategy with Apple products is to take the first upgrade for memory and storage and leave it at that. You can then resell every year and recoup 60% and upgrade to the latest w a new battery. Apple is actually very cheap after the first investment considering the productivity and time saving benefits, and you can’t steal an Apple device. Just don’t drop it
Also if you are considering big upgrades, compare the cost to just buying two base units as the base units are way closer to the manufacturing cost. Often there is more benefit to having two expendable units and they will hold their resale value better.
Unified memory literally is RAM. It's just LPDDR5. It might have better timings, due to being located closer, that's it. The framework 16 also does DDR5-5600, so you get 100GB/s of bandwidth with a dual rank memory setup.
In theory you'd take a latency hit, but in reality (at least the M1) was limited by it's memory controller and had DRAM latencies of ~100ns, which is actually worse than Zen 4 at ~70ns. This is because before querying RAM, you first need to query every level of cache, and then you hit the latency of the DRAM itself, so the actual distance is not a dominant factor.
So no, unified memory doesn't give any actual performance advantage. It could in theory (and marginally), in practice it's just marketing.
Apple doesn’t verify that purchases from the educational store are from students it’s honor system. Those prices are available to everyone, in small quantities.
Sit the 15 inch MBA next to the 16 inch MBP and the screens look identical. Performance wise the M2 w unified memory crushes X86 systems across the benchmarks at half the power budget.
