Recently, major SSD vendors Crucial and Western Digital have both been caught swapping out TLC NAND in their consumer SSDs for cheaper but much lower-performance, lower-endurance QLC NAND. Samsung appears to be joining them in the part-swapping corner of shame today, thanks to Chinese Youtuber 潮玩客, who documented a new version of the Samsung 970 Evo Plus using an inferior drive controller.

Although the consumer-facing model number of the drives did not change—it was a 970 Evo Plus last year, and it's still a 970 Evo Plus now—the manufacturer part number did. Unfortunately, the manufacturer part number isn't visible on the box the SSD comes in—as far as we've been able to determine, it's only shown on a small label on the drive itself.

Falling off the write cliff

We tested the 970 Evo Plus (alongside the 980, and the older 970 Pro) in March, clocking it at write speeds of 1,600+ MiB/sec on 1MiB workloads. Our benchmarking was done with he old version, part number MZVLB1T0HBLR. The newer version—part number MZVL21T0HBLU—is considerably slower. According to 潮玩客's test results, the newer version only manages 830MiB/sec—half the performance of the original.

Reuters reports that TSMC—Taiwan Semiconductor Manufacturing Company, the chip foundry making advanced processors for Apple, AMD, and Qualcomm—is beefing up its plans to build factories in Arizona while turning away from an advanced plant in Europe.

Last year, TSMC announced that it would invest $10-$12 billion to build a new 5 nm capable foundry near Phoenix, Arizona. According to Reuters' sources, TSMC officials are considering trebling the company's investment by building a $25 billion second factory capable of building 3 nm chips. More tentative plans are in the works for 2 nm foundries as the Phoenix campus grows over the next 10-15 years as well.

US President Joe Biden called for $50 billion to subsidize US chip manufacturing facilities, and the US Senate may take action on the item this week. Strong domestic manufacturing capacity is seen as critical, since US chip firms such as Nvidia and Qualcomm rely on Asian manufacturing facilities. TSMC would be competing with Samsung and Intel to secure these Biden administration subsidies.

It's that time of year when many TV manufacturers begin announcing prices for and shipping their annual product refreshes. We took a look at Sony's OLED lineup yesterday, but today we're turning our attention to Samsung, which just announced imminent availability (most models will start shipping this month) for its high-end Micro LED and MiniLED TV lineup.

We'll get to Micro LED in a minute, but let's start with the mainstream high-end, which are the MiniLED TVs. Samsung is giving these a proprietary "Neo QLED" label.

The top-end QN900A is the most tricked-out 8K option, with 65-inch ($5,000), 75-inch ($7,000), and 85-inch options ($9,000). One step down while keeping the 8K banner flying is the QN800A, offered in the same sizes but at $3,500, $4,700, and $6,500, respectively.

Samsung Electronics said a global semiconductor shortage that has hit global carmakers could also disrupt orders for the memory chips used in smartphones, as manufacturers rushed to respond to the crisis.

The warning from the world’s biggest memory chipmaker comes as companies and governments grow concerned that constrained chip manufacturing capacity could derail countries’ economic recoveries from the coronavirus pandemic.

The rush by semiconductor foundries to meet demand for auto chips means many are now operating at full capacity, limiting their ability to take on new orders, which could in turn slow deliveries of chips designed for mobile devices.
