No — core performance is effectively identical. The Slim is a size and internal-layout redesign, not a power upgrade, unlike the PS4 Pro relative to the standard PS4.
Sony followed the same playbook it used for the PS4 and PS3: a few years after launch, the original PS5 was replaced in production by a smaller, redesigned "Slim" model. The core performance is the same, but a few structural changes are worth knowing — especially the one affecting disc support.
The PS5 Slim is meaningfully smaller and lighter than the original launch model, achieved through a redesigned internal layout and cooling system rather than reduced components — core performance (CPU, GPU, effective SSD speed) is the same as the original PS5. Storage capacity on the internal SSD was also increased on Slim models compared to the original launch console.
This is the detail most casual comparisons miss: on the original PS5, the Digital Edition simply had no disc drive at all, permanently. On the PS5 Slim, Sony restructured this — the Slim's Digital Edition can have an official detachable disc drive accessory added after purchase, turning it into disc-capable hardware. This didn't exist as an option on the original launch Digital Edition. If disc support (now or possibly later) matters to you, this is the single most relevant hardware difference between the two generations, more so than size or weight.
Game compatibility, controllers, and accessories are all cross-compatible between the original PS5 and PS5 Slim — there's no game library difference between the two generations, unlike, say, Wii vs Wii U. Performance for existing games is effectively identical, since the Slim isn't a mid-generation power upgrade (unlike the PS4 Pro relative to the PS4) — it's a size/cost redesign of the same underlying hardware generation.
If you're buying new, the Slim has effectively replaced the original in current production and retail availability, making it the default choice by circumstance rather than a deliberate tradeoff. If you're buying secondhand and comparing the two directly: the Slim's smaller footprint and detachable-drive flexibility on Digital Edition units make it the more practical pick for most buyers, while the original launch PS5 mainly appeals to those who specifically want the console as it originally shipped. See our PS5 Digital vs Disc guide for the separate decision of which edition to get within either generation.

Yes, on Slim models Sony offers an official detachable disc drive accessory that adds disc support after purchase. This option did not exist for the original launch PS5 Digital Edition.
Yes — there is no game library difference between the two. All PS5 games and backwards-compatible PS4 titles work the same across both.
Only if you specifically want the original hardware as it originally shipped — the Slim is smaller, has more internal storage, and (on Digital Edition units) offers the option to add a disc drive later, which the original launch Digital Edition never supported.
