The inflation has really hit the consumer market... 700$ for CPU and over thousand for GPU... Memory is not cheap either... Not that it won't sell, but still these price points for something still called consumer start to be high. You could get a whole portable PC for same money.

I paid a bit more than that for my current 5950X a couple years ago now. Top of the stack CPUs have always had a pretty big price jump. Though, I would class the 7950X(3D) as similar to HEDT even if it's the top of the consumer models... if you don't need a ton of i/o, there's a lot of value there depending on what you're doing.

GPU pricing seems a bit more insane, given a lot of the demand has actually died down at this point, and the mfgs are definitely restricting production to keep prices (and margins) up. It's kind of sad there really isn't anything comparatively good on the lower pricing end ($100-300) where historically you'd see around 60-70% the performance well under half the price.

Why do people use M for Megabytes?

The way I understand it JEDEC had standardized KB/MB/GB being multiple-of-2-based in memory specs prior to the IEC standardising KiB/MiB/GiB for the same. As a result it kind of just stuck in the space since the idea of multiple-of-10 cache is a bit silly anyways so there is no risk for confusion.

AnandTech sees some intriguing regressions on certain benchmarks,

https://www.anandtech.com/show/18747/the-amd-ryzen-9-7950x3d... ("CPU Benchmark Performance: Simulation")

Worst is Factorio, which is down -47% against the 5800X3D (a previous-generation CPU that also uses stacked L3 cache), on the benchmark "10K trains". Wonder what's going on there?

- "We would have expected higher performance in our Factorio benchmark, as the Ryzen 7 5800X3D and its 3D V-Cache did yield some impressive gains. This is likely due to the AMD PPM Provisioning and 3D V-Cache driver opting for frequency over cache when running this benchmark."

The challenge is compounded by the fact that you need to buy a whole host of new parts at the same time. A new motherboard to handle AM5, DDR5 memory, and most likely a new PSU given how power hungry CPUs and graphics cards have become.

I saw on Hardware Unboxed that the non-X3D cores were being used for Factorio and that reviewer manually disabled it to test correctly.

I wish they'd included the results of the undervolted 7950x in the graphs (aka ECO mode) It's sad that performance benchmarks have made market conditions where the gain of 5% performance is somehow worth 20%-30% extra power consumption (and the noise that follows from that)

The X3D chips do at least have a reduced TDP of 120W vs 170W (except for the 7800X3D vs the confusingly comparable 7700X's 105W). The other thing is that, at least in DIY PC (and botique builders like CyberPower) the "gaming" motherboards universally increase the maximum peak power target and also commonly enable things like all core turbo and precision boost overdrive by default. So unless they specify otherwise, like AnandTech I think, you can assume most reviewers will be running the CPU with more power than the spec but that's a common situation for their audience.

Is it? Have a look at this article from 2002:

> With the cuts, the wholesale cost of a 733-MHz Pentium III drops 3 percent, from $776 to $754, while the 700-MHz version drops 3 percent from $754 to $733 in volume.

https://www.cnet.com/culture/intel-cuts-pentium-iii-prices-1...

$754 in today's dollars is over $1250.

Cutting edge processors are cheaper than they were 20 years ago.

Wow basically the same pref as a 13900k but so much less power usage in the aggregated tests. Apps : 79w vs 169w Games : 56w vs 143w

In my experience you can tune the i9-13900K way down on power and barely notice or not at all. I wouldn’t be surprised if these benchmarks came out the same way on the Intel side with power caps set at 125W.

You're wrong here. This is top-of-the line enthusiast CPU. They always have costed around 1k$, see e. g. Intel Core i9 Xtreme lineup (the chips with 'X' designation here: https://en.wikipedia.org/wiki/List_of_Intel_Core_i9_processo... ). You can have absolutely fine 8c16t CPU which will handle anything you can possibly throw at it for 230$ from Amazon ( https://www.amazon.com/AMD-Ryzen-5800X-16-Thread-Processor/d...…

I was actually wondering what the original Extreme Edition P4s retailed for a couple of decades ago, and it turns out to be $999. Plus ça change, plus c’est la même chose.
