AMD Ryzen 7 7800X3D review: faster than 13900K and 7950X3D for gaming? Here's digitalfoundry:
The one that we've been waiting for is here. The $449 Ryzen 7 7800X3D processor promises to deliver similar gaming performance to AMD's flagship 7950X3D and Intel's Core i9 13900K, while consuming less power and costing significantly less than its rivals.
Our expectations for the 7800X3D are high - after all, the CPU's design permits its full 120W TDP to be dedicated solely to an eight-core chiplet complete with performance-boosting 3D V-Cache. By comparison, the 7950X3D and 7900X3D released in February split that power budget across two chiplets, only one equipped with the extra L3 cache, so we could potentially see even greater performance than these CPUs.
Even getting close to its rivals in terms of frame-rate could put the 7800X3D in the same hallowed tier as, a reasonably affordable mid-range CPU that punches well above its weight and even challenges Intel's equivalent-generation flagship parts. Under the skin, the eight-core 7800X3D resembles the 12-core 7950X3D and 16-core 7950X3D - with just the 3D V-Cache chiplet enabled. The simpler design is less flexible, but has its advantages too.
You can see how the 7800X3D fits into AMD's Zen 4 lineup in the table below. As a reminder, each of these Ryzen 7000 desktop designs benefits from a range of advances over their Ryzen 5000 counterparts, with a quoted 13 percent uptick to instructions-per-clock and more internal improvements, like an improved execution engine and a better branch predictor. There's also DDR5 and PCIe 5.

Ethernet co-inventor finally bags a Turing Award, half a century laterScrew sports, Katie would rather watch Intel, AMD and Nvidia go at it. Having been obsessed with computers and graphics for three long decades, she took Game Art and Design up to Masters level at uni, and has been demystifying tech and science—rather sarcastically—for two years since. She can be found admiring AI advancements, scrambling for scintillating Raspberry Pi projects, preaching cybersecurity awareness, sighing over semiconductors, and gawping at the latest GPU upgrades. She's been heading the PCG Steam Deck content hike, while waiting patiently for her chance to upload her consciousness into the cloud.

Rapid antigen-based and rapid molecular tests for the detection of SARS-CoV-2: a rapid review with network meta-analysis of diagnostic test accuracy studies - BMC MedicineBackground The global spread of COVID-19 created an explosion in rapid tests with results in | 1 hour, but their relative performance characteristics are not fully understood yet. Our aim was to determine the most sensitive and specific rapid test for the diagnosis of SARS-CoV-2. Methods Design: Rapid review and diagnostic test accuracy network meta-analysis (DTA-NMA). Eligibility criteria: Randomized controlled trials (RCTs) and observational studies assessing rapid antigen and/or rapid molecular test(s) to detect SARS-CoV-2 in participants of any age, suspected or not with SARS-CoV-2 infection. Information sources: Embase, MEDLINE, and Cochrane Central Register of Controlled Trials, up to September 12, 2021. Outcome measures: Sensitivity and specificity of rapid antigen and molecular tests suitable for detecting SARS-CoV-2. Data extraction and risk of bias assessment: Screening of literature search results was conducted by one reviewer; data abstraction was completed by one reviewer and independently verified by a second reviewer. Risk of bias was not assessed in the included studies. Data synthesis: Random-effects meta-analysis and DTA-NMA. Results We included 93 studies (reported in 88 articles) relating to 36 rapid antigen tests in 104,961 participants and 23 rapid molecular tests in 10,449 participants. Overall, rapid antigen tests had a sensitivity of 0.75 (95% confidence interval 0.70–0.79) and specificity of 0.99 (0.98–0.99). Rapid antigen test sensitivity was higher when nasal or combined samples (e.g., combinations of nose, throat, mouth, or saliva samples) were used, but lower when nasopharyngeal samples were used, and in those classified as asymptomatic at the time of testing. Rapid molecular tests may result in fewer false negatives than rapid antigen tests (sensitivity: 0.93, 0.88–0.96; specificity: 0.98, 0.97–0.99). The tests with the highest sensitivity and specificity estimates were the Xpert Xpress rapid molecular test by Cepheid (sensitivity: 0.9

Nasal vaccine to prevent COVID-19 passes first testsCoronaviruses spread primarily through the air. When infected people speak, cough, sneeze or laugh, they expel droplets of saliva containing the virus. Other people then breathe in these airborne pathogens and become infected themselves. A research team in Berlin decided to try to fight the virus that causes COVID-19 where it first takes hold: the mucous membranes of the nose, mouth, throat, and lungs.
