The die shots show the IO section is on the other side of the die, and that there seems to be an area of unused silicon next to the FPU, which is close to if not matching the area "saved" by shrinking the FPU. Unused die area negates the supposed savings in transistors, as the cost of the die...

The mix tested points to a noticeable drop in peak IPC. There could be mixture-dependent differences, since it's not clear that the tests shown indicate if there's more or less contention with non-arithmetic ops things like moves and shuffles. The non-descript fpu mix tests might show that...

I'm not sure that provides a comparable scenario to what the benchmarking for the 4700S showed, which makes a Zen2 vs PS5 that has the SSE cut in half as well.

From the article, it's $6.9 million in compensatory and $130 million punitive. Ostensibly the latter part is more about correcting Tesla's behavior, although it's true such numbers tend to be cut down significantly if not mostly wiped out on appeals. Perhaps not coincidentally, corporations...

The APU reduces the amount of L3, which is a common sacrifice for mobile. The cores are architecturally the same, to my knowledge. Barring some Sony-specific reasoning, cutting the FPU doesn't have any clear justification. The laptop chips are not performance consistent, they aren't in a...

Going by the instruction profiling, it's not just AVX. The FPU is half as effective at 128-bit and 256-bit code, hence the same performance drop in SSE operations. Vector loads tend to stress AMD's boost speeds the most on the desktop, so power reduction would seem to be the motivator. However...

Without an actual comparison, it might be assuming too much about whether the PS5 was being compared to its competitor. Those numbers are decent, but from what I've seen in other reviews inferior to the standalone chiplet Zen2 products. The Zen2 APUs seemed to have even better inter-ccx...

The 10 GB is GPU optimized, but is not exclusive to the GPU. The 10 GB would be the range of addresses that can be equally strided over all the channels, with the remaining space being an extra 1GB on only some of the chips, which Microsoft seems to have decided to handle a little differently...

I think in this instance that if the GPU is not in-use that almost all the memory space is effectively non-GPU optimal. AMD's controllers in APUs were able to adjust stride patterns based on what was dedicated to the GPU in the past, so I don't think it would be stuck using GPU access...

Even significant inflation would take months to years to fully play out, and absolute terms likely would rank as a mild swing compared to what crypto can do on a bad day. Citizens trying to get out of the real estate bubble by evading capital controls would be buying crypto for the purposes of...

The problem where the base amount of bandwidth each client needs comes out of a single bus can't be helped. What was disclosed was that the PS4's bandwidth consumption with both CPU and GPU was worse than the sum of their bandwidths, due to interference between the different access patterns. In...

What alternate path are you considering for heat to leave the console? The case itself can get warm, but it's not a particularly effective path. The cooler-exhaust path is the dominant way to get heat out of the system, and if so then that path in both designs needs to transfer heat at the same...

It's possible that they might think a number of their claims aren't strong, but when dealing with contracts of this magnitude a legal filing for even a chance at hundreds of millions to billions of revenue seems like a decent gamble. Such disputes aren't uncommon in government procurement...

Anecdotally, some of those who tried to fix coil whine after excluding or fixing things like production stickers left in the fan grill, fan mounting issues, and noisier fan models, involved putting additional coating on components in the power supply block, which is separate from what has been...

Sony has been willing to mix its fan supply, so I wasn't sure if it was introduced with this revision. The infrared footage looks at a small volume of the case and metal that is in line of sight of the sensor. The exhausted air doesn't seem to be particularly emissive compared the the solid...
