Been a long time since I bought a new computer. How should I think about / compare the processor options of the new MBA[1] and the non-touchbar MBP[2]? I've seen the passmark results, but have no idea how to interpret.
[1]: 8th Gen 1.6-GHz dual-core Intel Core i5
[2]: 7th Gen 2.3GHz dual-core Intel Core i5
- jakobegger 8y agoAccording to Anandtech the new MBA has a 5W TDP Y series chip. The non-touchbar MBP has a 15W TDP U series chip. So I'd assume that the MBP is going to be a lot faster in practice, even though it's one generation older. https://www.anandtech.com/show/13531/apple-2018-macbook-air-announced https://www.anandtech.com/show/13531/apple-2018-macbook-air-...
- wodenokoto 8y agoI've been scratching my head on that point too. Apple's spec page list the MBA processor to have "4MB L3 cache", while the MBP non-touch bar processor is listed as having "64MB of eDRAM". I mean, 64 sounds better than 4, but are these things even comparable? is eDram something you have next to L3 cache or instead?
- Dunedan 8y agoThe eDRAM is mainly for the integrated GPU and an addition to the L3 cache. It's also only available for a few selected Intel CPUs, which usually have higher graphics performance. As Wikipedia puts it [1]: > The 128 MB of eDRAM in the Iris Pro GT3e is on the same package as the CPU, but in a separate die manufactured in a different process. Intel refers to this as a Level 4 cache, available to both CPU and GPU, naming it Crystalwell.
