You Block 175 Web Spiders And What Do You Get Edition
- Turns out what you get is lightning fast page loads because the server load is down below 10% again.
- Intel's MKL is a highly-optimised linear algebra library unless you have an AMD CPU in which case it's digital cancer. (Puget Systems)
It's twice as fast as OpenBLAS on Intel CPUs. It's three times slower on AMD CPUs: If it finds an AMD processor it drops all the way back to the SSE2 instruction set introduced twenty years ago.
Which makes me wonder if Intel used MKL in any of their benchmarks against Opteron. There's no way to tell from their slide decks, because they removed all such details.
- Qualcomm's "eight core" Snapdragon 8c and 7c are indeed 4+4 and 2+6 configurations. (AnandTech)
AnandTech didn't pin down the 7c precisely but Android Authority has those details.
AMD got sued for calling Bulldozer an eight core chip. (The Verge)
Given that six of the cores in the 7c run at literally half the speed of the first two, I wouldn't be surprised if Qualcomm found themselves in the firing line as well.
- 6.9GHz all cores. (Tom's Hardware)
With liquid nitrogen and a 1250W power supply (though the system "only" drew 650W).
Or you could skip all that nonsense and just get a Ryzen 3950X. Well, except that Newegg is out of stock even at a 20% markup and Amazon can't even find it to display an out of stock message.
Hey, AMD! Lower the bins by 300MHZ and sell a 3900 non-X for $650. You're welcome.
Also a server edition.
- An updated review of the Intel 660p SSD. (Tom's Hardware)
QLC has been out for a while now, and Tom's Hardware have returned to their original review to look at the 2TB model.
QLC write performance is, well, not great, but the 2TB 660p provides a 24GB SLC cache plus 1/8th the free space of the drive, so up to 280GB of cache on a brand new drive.
In theory that means that the drive should be about as fast as an SLC device - within its limit of a PCIe 3.0 x 2 connection, so up to about 2GB per second - unless you write data fast enough to fill that 280GB cache.
In practice, that's exactly what they found:
For over two minutes of writing, Intel’s SSD 660p wrote over 275GB of data at a rate of 1.8 GBps. After that, the SSD’s write performance fell significantly, down to just 175 MBps on average.Intel have announced the 665p, but it's a relatively minor update. It looks like either model would be just fine for desktop use.
- The PC died a decade ago next month. (ZDNet)
Ouch at this conclusion:
Maybe it wasn't the PC that died a decade ago. Maybe it was the Mac.
- Reddit has banned a subreddit and 61 accounts accused of being a Russian disinfo campaign targeting the British election. (Engadget)
A complete list and discussion. (Reddit)
All the usual suspects are hyperventilating over a campaign that seems to have had near zero impact. (Stars and Stripes)
A laptop with a 7c probably wouldn't be very performant, but people still buy low-end laptops.

Which is kind of funny since there's still a price premium.
