The new Apple M2-based MacBook Pro has half the SSD speed of last year’s Apple M1-based NGA model
Following the release of Apple’s new 13-inch MacBook Pro based on the Apple M2, the $1,300 base model with a 256GB SSD was found to have significantly slower read/write speeds compared to the equivalent previous generation model.
YouTube channel Max Tech and Created Tech tested this version with the Blackmagic Disk Speed Test app and found that the SSD read and write speeds are about 1450 MB/s, which is about 50% slower when reading and about 30% slower when writing. compared to a 13-inch Apple M1-based MacBook Pro with a 256GB SSD.
Max Tech results:
- 13″ MacBook Pro (M1/256GB) Read Speed: 2900
- 13″ MacBook Pro (M2/256GB) Read speed: 1446
- 13″ MacBook Pro (M1/256 GB) Write speed: 2215
- 13″ MacBook Pro (M2/256 GB) Write speed: 1463
Upon disassembly, the new 13-inch MacBook Pro with 256 GB of memory was found to have only one NAND flash chip, while the previous model had two NAND chips of 128 GB each. This difference probably explains why the new model has a slower SSD: multiple NAND chips in parallel provide faster speeds.
Perhaps this decision is due to lower costs and / or lack of components. Apple has not yet commented on the situation.

Samsung is preparing an “ultimate” SSD. The company teases with a promotional video with a new drive
Samsung has started teasing Twitter users with an advertisement for a new SSD. The company does not specify the details, calling the new Ultimate SSD.
Third-party sources expect this to be a new SSD (or a whole series) with a PCIe 5.0 interface. These may well be models of the Samsung 990 SSD line, which were previously lit up in the databases of regulators.
Samsung previously released the PM1743 PCIe 5.0 SSD for the data center, and it offers data transfer speeds of up to 14GB/s, so you can expect similar numbers from the 990 Pro.

Some motherboards will turn the Core i9-13900K into a power consumption monster. The power limit will increase to 350W
Intel can make the Core i9-13900K even more attractive with a new auto-overclocking mode.
The source reports that some motherboards based on 700-series chipsets will allow you to activate an increased power limit. In this case, we are talking about a value of 350 watts. For comparison, Alder Lake has a maximum of 241 watts.
The values of PL1 and PL2 for the new CPUs will hardly change and will amount to 125 and 253 W, respectively. But there will also be an opportunity to remove the limit, thanks to which the Core i9-13900K will be able to consume up to 350 watts. In this case, of course, the motherboard will need a powerful power supply subsystem, and the processor will need a productive CO.
CPU performance in this mode can increase by 15%, although this will depend on the tasks. Whether the Core i9-13900KS, which was previously assigned a frequency of up to 6 GHz, will be released under such conditions is now unclear.
The first photo of the Ryzen 7 7700X processor has appeared on the Web, which should be presented on August 29, and it is expected to go on sale on September 27.
Apparently, the picture shows a pre-sale version. Perhaps this is one of the copies for media reviews.
The Ryzen 7 7700X is an octa-core SMT capable CPU up to 5.4GHz with a TDP of 105W. According to leaks, such a processor will cost about $ 300, that is, it will not rise in price relative to its predecessor at the start of sales.
Recall, in addition to this model, a 16-core Ryzen 9 7950X, a 12-core Ryzen 9 7900X and a six-core Ryzen 5 7600X are also expected. Later the line may well expand.
