The first tests of the new MacBook Air, MacBook Pro and Mac Mini on the Apple M2 platform may disappoint potential buyers of these devices: it turned out that all these versions of Apple computers in their basic versions received slower SSDs than their predecessors on the SoC M1.
So, for example, the maximum read and write speeds of 512 GB SSD data in the 14-inch MacBook Pro on SoC M2, measured in the BlackMagic Disk Speed Test, were 2970 and 3150 MB / s, respectively. In comparison, the 512 GB SSD of the past MacBook Pro on SoC M1 in the same application shows read and write speeds of 4900 and 3950 MB / s, respectively. The difference is significant: the new model SSD is about 39% slower in reading data and 20% slower in writing it.
Decreased reading and writing speeds were also recorded for the MacBook Air and Mac Mini on the M2 with a 256 GB SSD. So, for example, if the read and write speeds of a 2020 Mac Mini on SoC M1, measured using Blackmagic Disk Speed Test, are 2854 and 2733 MB / s, respectively, then in the case of a 2023 Mac Mini on SoC M2, read and write speeds dropped by almost half – to 1482 and 1431 MB / s, respectively.
What is the reason for this “downgrade”? The thing is that Apple uses larger memory chips. So, for example, if the 2020 Mac Mini has two 128 GB NAND chips, then the 2023 model has only one NAND chip (this, by the way, also applies to the model with 512 GB of memory). Accordingly, two chips allow you to perform read and write operations in parallel, but one does not. The 2023 MacBook Pro in the example above only has two memory chips, while its predecessor had four.
The good news is that in top configurations, the new 14- and 16-inch MacBook Pros with 1-2TB SSDs are just as fast as their predecessors.
AMD Ryzen 7000 processors have fallen in price in the US. 8-core Ryzen 7700X drops $104, top-end 16-core Ryzen 9 7950X drops $210
AMD Ryzen 7000 processors continue to get cheaper in the US, and from different retailers, and not somewhere in one place. So, prices have decreased on Amazon, and at Microcenter, and on the Newegg site.
The best deal on the Ryzen 7 7700X is $345. The processor dropped 104 dollars from the official price. For comparison, for its rival in the face of the Core i7-13700K in the US they ask for $418.
The 12-core Ryzen 9 7900X has fallen in price more – by $ 132: the cost has decreased from the official $ 550 to $ 418. That is, there is just price parity with the Core i7-13700K.
The top 16-core Ryzen 9 7950X dropped $211 from $800 to $589. For the Core i9-13900K in the US, they ask for only a little more – $ 598.
These are prices on the Amazon site, but Microcenter has about the same discounts. At the same time, the Newegg and Microcenter sites have already fallen in price and the latest 65-watt Ryzen 7700 – by $ 10, but nonetheless. Recall that the Ryzen 7000 (without the X index) was presented only in early January.
Read speed up to 10 GB/s and cooling system with a fan. Corsair Announces Flagship MP700 SSD with PCIe 5.0 Support
Corsair has announced its flagship M.2 SSD, the MP700. The novelty, apparently, will go on sale in the coming months, but its cost has not yet been reported.
But the maximum data transfer rates for sequential reading and writing are known – 10 and 9.5 GB / s, respectively. In the picture below, Corsair even compared its current top-end MP600 Pro XT SSD to the MP700. The difference is noticeable.
However, the MP700 will be able to fully realize its high-speed potential only on the latest platforms from AMD (with processor socket AM5) and Intel (based on 600 and 700 series chipsets). The creators talk about the use of 3D TLC NAND memory chips in the SSD and support for NVMe 2.0 M.2.
AMD promised SSDs with PCIe 5.0 support back in November last year, but in fact there are only a few such models on sale.
Noctua has unveiled the NH-L9a low profile cooler for AMD AM5 processors. It is compatible with 65W Ryzen 7000 CPUs
Noctua’s range of CPU coolers has been expanded with the NH-L9a model for AMD’s latest Ryzen 7000 processors. With a height of only 37 mm, the NH-L9a can be used in very compact cases.
Obviously, due to its compact size, the cooler’s ability to dissipate heat is seriously limited – it is suitable for cooling Ryzen 7000 processors with a TDP of 65W. The design is a low radiator with two heat pipes and a fan with a diameter of 92 mm. The regular version of the NH-L9a is priced at $45, while the all-black version costs $10 more.
