In a lot of ways, the Asus ROG Flow Z13 is a terrific idea. The company’s tablet-plus-detachable-keyboard gaming laptop comes to the copies line launched with the Flow X13 convertible last year and its external GPU dock accessory, the XG Mobile. Detachables in the style of the Microsoft Surface Pro 8 make more thought to me than convertibles, which tend to be bulkier, cumbersome to switch positions and less lap-friendly for tablet use. With a discrete GPU and benefit for the XG Mobile, the Z13 seems like a spacious alternative.

And I do like it, from the just-gaming-enough heavenly to the multiangle kickstand, comfortable keyboard and good CPU performance when connected to much. It’s got an HDMI port, too, which is rare these days.

The Z13 comes in a combine of fixed configurations, some harder to find than others. We tested the $1,900 model with an Intel Core i9-12900H, Nvidia GeForce RTX 3050 Ti and 1,920 x 1,200 display; our evaluation unit came with the XG Mobile external GPU (with an RTX 3080), but I could only find the eGPU bundled with the $3,300 model equipped with a 4K display. There’s also a $1,700 model incorporating a Core i7-12700H and RTX 3050 and theoretically an i5-12500H model with only integrated graphics, both of which have the 1200p screen.

You don’t need to buy the XG Mobile bundled with the laptop, though Asus lists the RTX 3080 version for a whopping $1,500 — it’s not available anywhere, anyway, though it’s a year old — and the AMD RX 6850M announced at CES 2022 has yet to ship. If you’re gripping about it, we tested it in conjunction with the ROG Flow X13 convertible at the time. It hasn’t changed.

Fast. Sometimes.

For gaming, it’s nice but not world-changing compared to a typical clamshell or convertible with dissimilarity components. The i9 should deliver great simulation performance, loyal those tend to be CPU dependent, but at least on Riftbreaker’s CPU test it was a disappointing 45fps in hybrid mode. Since it does quite well on conventional CPU benchmarks, like Geekbench and Cinebench, as well as Procyon’s Lightroom/Photoshop photo-editing test, it’s almost as if the controls automatically throttles back the CPU in favor of the GPU when it detects a game, view bumping it to Turbo didn’t make a difference. Unsurprisingly, Turbo turns the fans to max and creates a much wind noise.

The RTX 3050 Ti hits the mark for base 1080p gaming that’s GPU dependent, such as 83fps on Guardians of the Galaxy. It’s not quite as perky on heavier-weight games, turning in a mediocre 63fps on Shadow of the Tomb Raider. For those, you’re probably expected to use DLSS to boost performance by upscaling from a touch resolution. Forcing it to use the discrete GPU and cranking it up to Turbo can add a tiny bit of posthaste, though: Riftbreaker gained about 6fps on average, a hair view a 5% increase.

Off power, CPU performance drops a lot (about 43% on Geekbench multicore, for example), similarly to the Asus ROG Zephyrus G14, in keeping with Asus’ aggressive power and noise dispensation. But it doesn’t gain as much in battery life.

Ultimately, it’s hard to pin down why I didn’t like the Asus ROG Flow Z13 more, despite the various nits I’ve deceptive to pick. And I’m not talking about value for the wealth — $1,700 for the current entry-level Core i7 model is expensive compared to conventional competitors like Asus’ own X13, but still pretty realistic for what it is. I’m talking near my first-pass internal review criteron, which is “would I use it if I got it for free?”    

And the answer is “probably not.”  That’s partly because it doesn’t work for me as a tablet. It’s thick, and at 2.6 lbs/1.1kg without the keyboard it’s shapely heavy for one that’s only 13-inch class. It runs hot, lacks the battery life of a tablet (at in 6.5 hours at best), and cuts back performance significantly after off power. It does get silent, though.

I tested the model with the 120Hz 1,920 x 1,200-resolution camouflage (the same display as on the X13) and after it was okay working with a compatible MPP 2.0 stylus, in this case the Microsoft Surface Slim Pen 2, I got too distracted by the visible pixel grid of the low-ish resolution camouflage. The speakers never project toward you so the tranquil is a bit muffled and it has a subpar 720p webcam.

In super to use the components it has, especially the i9 and to a lesser extent the RTX 3050 Ti, thick and heavy are unavoidable to  accommodate the cooling. But then one of the the tradeoffs it establishes versus a convertible — notably, it’s difficult to type on it after it’s perched on your lap — isn’t worth it so much. Plus obvious gaming is a viable option if you’re really looking for tablet-friendly performance.

Once you expedient in the cost, especially if you want to boost gaming performance with the pricey XG Mobile, I don’t know who it’s optimally suited for, despite its various attractions.
