The conclusion alluded to one of the most interesting parts of how Jaguar may age -- summarized horribly -- we've never had a SOC shared between consoles (XB1/PS4), desktops, laptops and tablets so closely that as the SOC shrinks and the software on it is optimized further and further, you could imagine a future in short-order (3-4 years?) where you might be able to buy a much-shrunk Jaguar-based tablet that plays PS4 games at full fidelity.
His point is this has the potential of greatly extending the life of the Jaguar SOC just by virtue of die shrinks and power savings and no significant rejiggering of performance through the generations.
I thought that was a good call out... we never had this apples-to-almost-apples comparison before to see this story play out.
- pekk 13y agoAre PS4 games written to use a tablet's touch input effectively?
- ehsanu1 13y agoIf running PS4 (or PS5/6/7) games on tablets becomes a reality, you'd still use a hand-help controller most likely, at least until there's some bigger transition in gaming (VR controllers etc).
- sliverstorm 13y agoDoubtful, but don't the PS4 controllers connect using Bluetooth?

- cc439 13y agoThe CPU side can definitely be matched but packing in the GPU power would take a lifecycle at least as long as the last console generations. Personally I'm dismayed by the level of CPU performance found in the new consoles. Last generation quickly ran into a roadblock posed by the limited memory capacity but I think developers have been hamstrung by a lack of CPU horsepower right out of the gate. This is coming from a total layman who can only interpret benchmarks but I know that Jaguar's IPC is very weak compared to every other modern x86 design and the power of a single thread is a huge limitation no matter how much you try to program around it.
- cpleppert 13y agoI think the CPU story is pretty reasonable this console generation. You trade single thread performance for a more powerful and space efficient design. It is just a lot easier to optimize the CPU than the GPU especially running on a gaming focused platform so console makers always trade CPU for extra graphics power.
- tomlu 13y agoEver since the PS3 games are very good at taking advantage of multiple cores due to extensive use of data oriented design. Consequently in my experience single-threaded performance isn't as important as you might think.
- unsigner 13y agoPS3 games made everyone learn to take advantage of multiple cores, but the incredible single-thread (more like thread and a half with careful manual scheduling) performance of the SPUs should not be discounted.
- lucian1900 13y agoThe SPUs were fast, but still a simple design. Some workloads are entirely inappropriate for them. However, lots of generic CPUs will be perform well enough for any task, so more of the overall workload can be expressed as asynchronous tasks. Game devs aren't complaining about the CPU performance.
