If you're looking for the most powerful mini PC you can get under $500, I've found it - after a lot of searching ahead of Prime Day, it turns out the real deal is over at Newegg, where the Brenuc Bren7P mini PC is down to $499 (was $599) right now.
This compact desktop is powered by the AMD Ryzen 7 7840HS — a high-performance 8-core, 16-thread Zen 4 chip with a 5.1GHz boost clock that sits comfortably at the top of the mini PC performance tier. Paired with DDR5 memory, a PCIe 4.0 SSD, and dual 2.5G Ethernet, this is a machine that genuinely earns the “powerful” label without needing a large chassis to do it.
The AMD Radeon 780M is the upgrade that really caught my eye. For video editors using hardware acceleration in DaVinci Resolve or Premiere, photographers using GPU-accelerated processing in Lightroom, or developers running GPU-compute workloads, the difference is immediately tangible. It also handles a broader range of gaming titles than Intel’s integrated graphics at playable frame rates.
Today's top mini PC dealFor the price, this is the most powerful mini PC - or PC of any size - you can get for less than $500. And that's because it's packing the high-performance Ryzen 7 7840HS, 16GB DDR5, 512GB PCIe 4.0 SSD, and AMD’s Radeon 780M GPU. That makes a real difference for anything visually demanding, from photo and video editing to light gaming. You can even upgrade to 64GB RAM and dual M.2 NVMe storage.View Deal
The AMD Ryzen 7 7840HS is the real engine here. It’s a Zen 4 processor built on TSMC’s 4nm process — the same generation as the chips AMD put in its premium gaming handhelds — and it consistently benchmarks among the strongest mobile CPUs in the 15W–54W power envelope. Eight performance cores with simultaneous multithreading and a 5.1 GHz boost clock mean this chip handles sustained multi-threaded workloads like video transcoding, compiling, data processing, and running virtual machines without throttling, as lower-TDP mobile chips often do in compact chassis.
The dual 2.5G Ethernet ports are a standout feature in this category. Most mini PCs at this price ship with a single 1G port; dual 2.5G gives you 2.5 times the bandwidth per port and the ability to connect to two separate networks simultaneously. For home office users who keep work and personal networks separate, IT professionals who need multiple network interfaces, or anyone running a network-attached storage server or a home lab, this is a genuinely practical inclusion you’d typically pay more for.
USB 4.0 at 40 Gbps on the rear I/O is another connectivity highlight. At full bandwidth, it’s four times faster than USB 3.2 Gen 2, and it supports DisplayPort Alt Mode, Power Delivery, and Thunderbolt 3-compatible devices. In practice, you can connect an external SSD and transfer a 4K video library in a fraction of the time it would take over USB 3.2, or connect a high-res display and still have bandwidth left over for data.
The triple 4K display capability (HDMI 2.0, DP 1.4, USB-C) mirrors what the KAMRUI H2 offers, and the dual M.2 NVMe PCIe Gen 4 slots support up to 64GB of DDR5 RAM and as much storage as you want. The tool-free interior access — four base screws and a pull tab — makes upgrades straightforward without needing specialist equipment.
Right now, the Brenuc Bren7P is the most well-rounded mini PC you can currently find under $500 — and the Radeon 780M is what tips it over the line. Check out more options in our guide to the best mini PCs.
It's a tale as old as tech time: a new flagship device appears on the scene, which means the device it's replacing gets a price drop, and potentially offers better value for money for the discerning gadget buyer.
For this guide, we're going to be looking specifically at the Oura Ring 4 (which launched in 2024) and the Oura Ring 5 (launched in 2026). The Oura Ring 4 is likely to see some great Amazon Prime Day deals, but should you go all in on the latest and most expensive model? Or is the older model the better investment when bought at a discount?

There's no doubt that both models qualify as two of the best smart rings on the market right now, but which one is right for you depends on your budget and what your priorities are. Here's how they compare.
Oura Ring 5 vs Oura Ring 4: pricingThe (Image credit: Oura)While pricing varies as special offers come and go, the Oura Ring 5 launched for a starting price of $399 / £399 / AU$649, with some finishes costing extra at $499 / £499 / AU$799 – that's a little more expensive than the original Oura Ring 4 (note that the prices for Australia are for third-party resellers, not from Oura directly).
There's an upgraded charging case available for $99 / £99 / AU$159 for the Oura Ring 5, and then there's the monthly subscription: $5.99 / £5.99 / AU$9.99 a month or $69.99 / £69.99 / AU$109.99 a year. While a subscription isn't technically necessary to use an Oura Ring, you do need one to access the bulk of its features.
So what about Oura Ring 4 price drops? At the time of writing, the starting price is $349 / £349 if you go through the official channels, and we're seeing some good deals on the Oura Ring 4 already, which you can find below. Given that it's an older model, you're much more likely to see discounts on this smart ring on both the Oura shop and third-party retailers like Amazon.
Oura Ring 5 vs Oura Ring 4: specs and featuresThe Oura Ring 4 launched in 2024 (Image credit: Oura)What you need to know first is that the Oura Ring 5 is notably slimmer than the Oura Ring 4: for the most affordable finishes, it's 6.09 mm (0.24 inches) wide and 2.28 mm (0.09 inches) thick, down from 7.9 mm (0.31 inches) and 2.8 mm (0.11 inches), which is a reduction of about 40%.
That can make a difference when it comes to comfort and day-to-day wear. The new model is lighter too, with those reduced dimensions, weighing 2 grams rather than 3.3 grams. Both models are available in a variety of ring sizes to fit your finger, though the Oura Ring 5 introduces a new sizing scheme that doesn't match its predecessor.
The new, slimmer Oura Ring 5 (Image credit: Oura)The Oura Ring 5 is also more scratch resistant, while both models offer the same level of waterproofing (down to a depth of 100 meters). Battery life has been improved on the new model too, with the official estimates standing at 5-8 days for the Oura Ring 4, and 6-9 days for the Oura Ring 5.
As for sensors and health tracking features, this is where the rings are mostly tied. Oura says the fifth-generation model is more accurate because of a change in the sensor layout, but the core sensor tech is the same between the two models, and the software experience through the app is the same for tracking steps, activity, heart rate, and more.
Oura Ring 5 vs Oura Ring 4: VerdictThe Oura Ring 4 is still an excellent smart ring (Image credit: Oura)There's clearly a lot that's new and improved in the Oura Ring 5: it's slimmer and lighter, and offers better battery life. Oura says it's also more accurate, though that's not something we've finished testing ourselves just yet. That said, the tracking capabilities, sensors, and app features are more or less identical between the models.
Where the Oura Ring 4 really has the potential to outdo the newer model is in terms of pricing. As time goes on, you're likely to see bigger and bigger discounts on the fourth-generation model — and don't forget that we awarded it our Health & Fitness Device of the Year award for 2025. It's a seriously impressive bit of kit, and if the right discount comes along during Amazon Prime Day, it'll certainly be a better-value package than the Ring 5.
Regardless, you'll need to weigh up what's most important to you for your next smart ring, and how much you're prepared to spend to get it. Both of these premium smart rings from Oura will give you years of use — so we might be talking about the Oura Ring 6 before you need to think about upgrading again.
