I went to a computer store recently, and told them that I was interested in dropping about 2k on a laptop, and I brought a list of specs (at least 16gb ram, lots of cores, etc.). He suggested I should get a gaming laptop and never gave any suggestions from his store.
It will be interesting to see what the future holds, because they're already getting close to the physical limits of what they can build in terms of processors. If they start slowing down financially, it may be the case that we'll still be using computers that are about as fast as they are today in 7-10 years from now.

- khuey 11y agoMost software workloads can't use 128 cores in any useful fashion.
- dragandj 11y agoThe problem is that most applications have to be completely rewritten for parallel algorithms, which does not fit well to many application domains (does not bring additional speed).
- sounds 11y agoYour laptop already has a GPU, which has more cores than that. Let's take the segment of the market with an NVidia GPU. They have CUDA, one of the most polished development environments for GPGPU today. When was the last time you wrote something in CUDA? What was it for?
- dragandj 11y agoInterestingly enough, I doubt any of the GPUs actually has even 128 physical independent cores (cuda cores are not actual cores).
- sgift 11y agoWhile a nice idea most software cannot even use 4 or 8 cores properly. That's one of the reason Intel CPUs are still king compared to AMD in desktop space. If you can use all of that cores AMD tries to cram in their CPUs you can get good performance for a good price, but the single-threaded performance is an absolute desaster at the moment (and the one thing AMD has focused most on for their next architecture, Zen), which is still what many workloads use.
