HP HP - 645 G9 14" Refurbished Laptop - AMD Ryzen 5 Pro 5675U with 32GB RAM - AMD Radeon Graphics - 512GB SSD - Silver Review
This refurbished HP laptop packs 32GB of RAM into a light body, but its older processor creates a major trade-off. We dig into the data to see if it's a smart buy.
The 30-Second Version
This refurbished HP EliteBook is a multitasking monster with 32GB of RAM in a light body, but it's powered by an older, slower processor. It's a great deal for under $450 if you need to run tons of apps at once and don't care about gaming or a great screen. For anyone else, its weak CPU and graphics make it a poor choice. Shop around, prices vary wildly from $413 to $731.
Overview
This HP EliteBook 645 G9 is a refurbished business laptop that's trying to do a lot with a little. It's packing a surprising amount of RAM into a very portable chassis, but it's built around a processor that's a few generations behind. For someone who needs to run a ton of browser tabs and office apps without lugging a heavy machine around, this could be a clever pick. But if you're expecting cutting-edge speed or a dazzling screen, you'll be disappointed.
It's squarely aimed at business users, students on a budget, or anyone who prioritizes portability and multitasking muscle over raw computing power. The 32GB of RAM is the headline here, a spec that's usually reserved for much more expensive machines. That makes it interesting because it's a bit of a paradox: a laptop with a middling CPU but a top-tier amount of memory.
We're looking at a refurbished model, which means it's been professionally restored to working condition. That's a key part of the story here, because it lets HP offer this configuration at a price that makes the 32GB RAM seem like a steal. It's not a flashy new Copilot+ PC, but it's a practical, no-frills tool for getting work done.
Performance
Let's talk about what those numbers mean. The AMD Ryzen 5 Pro 5675U is a 6-core chip from the 5000 series. In our database, its performance lands in the 32nd percentile for CPUs. That's middle of the pack, or a bit below. It's solid for everyday tasks like word processing, spreadsheets, and web browsing, but it's not going to blaze through video encoding or complex data analysis. You'll feel it lag if you push it hard.
The integrated AMD Radeon graphics are even more limited, sitting in the 18th percentile. This is not a machine for gaming or creative work. The 'casual gaming' mention in the specs is optimistic. You might get by with very simple 2D games, but anything with modern 3D graphics will struggle. The performance story here is all about that 32GB of RAM (71st percentile). It means you can have dozens of applications open simultaneously without the system slowing down or freezing. It's a multitasking powerhouse, even if the engine driving it isn't the fastest.

Value & Pricing
The tricky part here is the price. We see it listed from $413 to $731 across different vendors. That's a huge spread. At the low end, around $413, this laptop becomes a fascinating value proposition. You're getting 32GB of RAM and a portable business laptop for a price usually associated with 8GB machines. At the high end, near $731, it's a harder sell, as you're paying more for an older processor.
The value is entirely in the RAM-to-price ratio, especially if you find it at the lower end of that range. You're sacrificing CPU power, screen quality, and graphics performance to get that RAM bump and portability. It's a trade-off, but for the right user, it could be a smart one.
Price History
vs Competition
If you're looking at this HP, you should also consider the ASUS ProArt PX13 or a Microsoft Surface Laptop. The ASUS ProArt is a Copilot+ PC with a blistering AMD Ryzen AI 9 HX 370 processor, an RTX 4050 GPU, and a stunning OLED screen. It's a true creative workstation, but it'll cost significantly more. The trade-off is clear: the HP gives you more RAM and ports for less money, but the ASUS offers vastly better performance in every other area.
The Microsoft Surface Laptop (Copilot+ PC) is another premium alternative. It'll have better AI features, a nicer build, and a more modern processor, but again, at a much higher price and likely with less RAM. For gaming, the Lenovo Legion Pro 7i is in a completely different league. And if you're in the Apple ecosystem, the MacBook Pro M4 is the performance king. This HP EliteBook sits in its own niche: maximum multitasking RAM and portability on a tight budget, accepting older components to make that happen.

Common Questions
Q: Is 32GB of RAM overkill for this laptop?
For this specific laptop, yes, it's arguably overkill given the older Ryzen 5 Pro processor. The CPU can't fully leverage that massive memory for high-performance tasks. However, it eliminates any multitasking slowdowns. You'll never run out of RAM, even with 50 browser tabs, a video call, and office apps open, which is the main benefit here.
Q: How good is the screen for everyday work?
The 14" Full HD screen ranks in the 17th percentile in our database, which is disappointing. It'll be fine for documents, spreadsheets, and web browsing, but it won't be vibrant or sharp compared to modern laptops. It's a functional panel, not an enjoyable one. If screen quality is important to you, look elsewhere.
Q: Can I do any gaming on this laptop?
Realistically, no. The integrated AMD Radeon graphics rank in the 18th percentile, which is a weak spot. It might handle very old or simple 2D games, but any modern gaming, even at low settings, will be a struggle. This is not a gaming laptop. Its gaming score in our system is 11.6 out of 100.
Q: What does 'refurbished' mean, and is it reliable?
Refurbished means the laptop has been professionally inspected, repaired if necessary, and restored to working condition. It's not brand new. Reliability scores for this model are mediocre (26th percentile), so while it should work, it may carry a higher risk of future issues than a new model. Always buy refurbished from a reputable vendor with a good warranty.
Who Should Skip This
Gamers and creative professionals should skip this immediately. The integrated graphics are among the worst we've seen for that use, and the CPU isn't strong enough for rendering or editing. Look at the ASUS ProArt or Lenovo Legion instead.
Anyone who needs a fast processor for development, data analysis, or scientific computing should also avoid it. The Ryzen 5 Pro 5675U is underwhelming and will feel slow. You'd be better off with a newer Ryzen 7 or Intel Core i5 machine, even if it has only 16GB of RAM. Finally, if you care about screen quality or a premium build, the basic display and refurbished status won't satisfy you. Consider a Surface Laptop or a MacBook Air.
Verdict
For a business user, student, or remote worker who needs to run a massive number of applications simultaneously and travel light, this HP EliteBook 645 G9 is a compelling choice, especially if you find it for around $413. The 32GB RAM is a game-changer for workflow, and the port selection is excellent. Just know you're getting an older, slower processor and a basic screen.
We'd steer anyone else away. Gamers, creative professionals, or anyone who needs a fast CPU for coding, data science, or video editing should look at the competitors mentioned above. This laptop's strengths are too narrow for general use. It's a specialist tool, not a daily driver for most people.
