Intel regains diyy market share advantage:
According to BCNR's analysis of the Japanese DIY market, Intel desktop CPU sales have continued to grow alongside AMD Ryzen™s continued shortages, capturing 74% of the market share last month.
The data below aggregates sales from offline retailers and online sales in Japan, with the most popular Ryzen™ 5 Series share reaching 40.4% at one point in June 2020 before sliding all the way down to 12.6% now.
PassMark's desktop CPU market share data also shows Intel's strong recovery since the launch of the 12th generation Core. Intel has successfully increased Intel 7 process capacity, while AMD still needs to compete with TSMC customers such as Qualcomm for limited capacity, and has long lacked layout on mid-range and entry-level desktop models.
The highly anticipated Ryzen 7 5800X3D has been undecided, users have unknown prospects for the AM4 platform on the eve of the launch of the ZEN4 architecture Ryzen™ 7000, and long-term refusal to relax on the issue of supporting the Ryzen™5000 processor on the 300/400 series motherboards, which may also have had an impact on AMD's decline in the desktop DIY market.
The test shows that half of the SSDs have hidden power failure data safety hazards:
Russ Bishop, a netizen, shared his recent test findings: Half of the 4 consumer SSDs initially tested had power-out data security risks: even after performing a write cache flush, the data just written still could not survive the subsequent power outage.
Windows "enables write caching on the device" by default so that the operating system can continue with other work without waiting for the write to complete. However, to prevent data loss due to unplanned power outages or system failures, Windows also performs a regular write buffer flush to ensure that data is actually written to disk (HDD)/flash memory (SSD).
According to common sense, whether it is a mechanical or solid-state drive, the cache refresh command should be completed after the data is actually written to the non-volatile storage media.
However, Russ Bishop found after testing 4 SSDs that only the Samsung 970EVO Plus and the Western Digital Red Disk SN700 did not lose data after refreshing the cache, and SK Hynix's Gold P31 and Sabrent Rocket's SSD lied about the completion of the cache refresh when the data had not yet been written to the flash memory, and the result was data loss after the power failure.
Russ Bishop said he has ordered more SSDs to test: Intel 670P, Samsung 980, Western Digital Black Disk SN750, Western Digital Green Disk SN350, Kingston NV1, Seagate FireCuda 530, Ylredt P2, Inronex P5 Plus, covering different positioning NVMe SSDs from entry-level to high-end, and the PCEVA evaluation room will continue to pay attention to his test results.
