MSI Katana 15 Review (B13VGK-484US)
Source: Digit week
The MSI Katana 15 occupies an upper spot in the budget gaming laptop category. With an asking price of around $15000, the Katana 15 checks all the right boxes with a strong Intel Core i7-13620H processor, 16GB of RAM, and a 1TB SSD. That’s impressive given that most gaming laptops at that price point give you just 8GB of RAM and a 512GB SSD (or smaller). The Nvidia GeForce RTX 4070 makes the deal even better, and this is likely to be the new standard for low-priced, midrange gaming laptops, a spot previously reserved for the RTX 3070. On the other hand, the display is mediocre at best, favoring a high refresh rate over image quality. Additionally, the plastic chassis is uninspiring, and the short battery life significantly lags behind its peers. But they are not dealbreakers, but just worth keeping in mind when comparing it with competitors out there.

MSI Katana 15 (2023) Review
Source: USA Today
The MSI Katana 15 provides an affordable on-ramp to the newest generation of gaming laptops. There’s no mistaking the RTX 4070 and Intel Core i7-13620H’s potent combination, especially with Nvidia-specific features like DLSS, 144Hz display, and a MUX switch. Getting a new laptop at such an affordable price comes with important trade-offs, though. Battery life is abysmal and you can’t buy a small GaN charger to replace the laptop’s bulky AC adapter because the only USB-C port lacks power delivery. The screen is also quite dim and dull. For another $250, something like the Gigabyte AORUS 15 offers a brighter display and the largest battery possible for about triple the battery life. But MSI’s Katana 15 is still a good option if you want the highest frame rates possible while saving as much money as possible. It won’t blow you away with the screen, battery life, or materials, but it’s an option worth considering.

MSI Katana 15 (2023) Review
Source: PC Mag
If you're a strict utilitarian when it comes to gaming hardware, you can go right ahead and buy the MSI Katana 15. This gaming rig has substantial power and a fine price to match. Even if its design leaves a lot to be desired, it's not flimsy or frail or starved for cooling. Finding a similarly configured Lenovo Legion will likely provide a better all-around experience, but it's hard to ignore the price/performance ratio MSI brings to the table here (especially with a lower-end configuration selling for $999 at Micro Center(Opens in a new window)). For that, we highly recommend the 2023 MSI Katana 15...if you can see past the screen shortcomings.

MSI Katana 15 review — Phenomenal performance in a lackluster display
Source: Laptop Mag
The Katana 15 is a beast of a gaming laptop for those who refuse to spend anything over $2,000. With its phenomenal RTX 40-series graphics performance and great productivity scores, it’s hard to say no when faced with such powerful hardware at this price. We were also impressed by its aesthetically alluring design, satisfying keyboard, decent sound system, and its additional functionality that will make nitpicky gamers happy. The $1,599 price tag isn’t some sort of miracle, however, as the Katana 15’s incredible performance comes at the detriment of its battery life and display. Graphics performance is important, but it will feel nowhere near as impactful if the screen it’s attached to presents environments without their luster, while also being held back by shockingly dim peak brightness. Its sub-three hour battery life does it no favors, either. While you could just connect the laptop to a superior monitor or TV, if you’re looking for something with a gloriously colorful display and are willing to deal with worse gaming performance, we recommend the MSI Crosshair 15 R6E. If you don’t particularly care, the Katana 15 is an otherwise phenomenal gaming laptop.

MSI Katana 15 review (B13V, 2023): A good gaming laptop but a dull display
Source: Expert Reviews
There’s a lot to like about the latest Katana from MSI. It’s compact, graced with a good keyboard and a decent sound system, while performance – both gaming and general – is very impressive. It would have been impossible to recommend with a price of £1,500 thanks to the sub-par display and wretched battery life but, at £1,200, the failings are a little easier to swallow. That said, a half-decent 165Hz display and an 80Wh+ battery is not a ridiculous ask for that sort of money.

MSI Katana 15 (B13V) review – the generational leap is huge but the price is not very pleasant
Source: Laptop Media
Like in the past, MSI’s Katana 15 has its downsides. But thanks to the early adoption of the RTX 4000 GPUs, this device can become a best seller in no time. In fact, NVIDIA’s RTX 4050 shows an incredible performance jump, making it not only obliterate the RTX 3050 and RTX 3050 Ti, but also trade blows, and even beat the RTX 3060. Unfortunately, this leads to some shenanigans with the pricing of the new laptops. The Katana, which was known for its low price (hence more than one cost-cutting compromise), now is not so friendly towards your budget. This makes it pretty hard to recommend. But what are the aforementioned compromises in the case of the Katana 15 (B13V)? Well, let’s start with the all-plastic build. It doesn’t feel cheap, but its chassis is a little flexy. Not to mention the bouncy lid. Indeed, now all models receive a 4-zone RGB backlit keyboard, but the touchpad is far from the likes of the Lenovo Legion 5 from 2022 for example. Not only that, but there is no Thunderbolt 4 connection, and one of the USB Type-As runs at 2.0 speeds
