Upgrade Core I5 9400F to I7 8700/9700
Upgrade Core I5 9400F to I7 8700/9700
Hey! I've been browsing the used market searching for a refresh, and I'm eyeing the I7 9700 and 8700 models. My question is, which one suits my needs better? The 8700 offers double threads while the 9700 has two extra cores. I'm still figuring it out. My main goal is gaming with Discord, OBS, and other apps running simultaneously. My current 9400F works fine for just gaming, but it starts to struggle when I add more tasks—games often freeze briefly (~0.2 seconds), and the CPU stays near full capacity. I’m not really chasing higher FPS; instead, I want more stability and the ability to run other programs without getting CPU-heavy. My GPU is outdated, so I’m more concerned about performance smoothness than raw speed. The K variants are an option, but they mainly boost turbo clocks slightly (around 0.1ghz), which isn’t a big issue unless you need it. I’m leaning toward getting the 8700 or 9700, but mainly because of the extra cores and better multitasking potential. My setup runs on an Asus H310M-E R2.0 with 2x16GB RAM, Gigabyte GeForce GTX 1050TI Windforce OC, and a single 120mm AIO cooler. I’m curious—should I go for more cores with a bit higher clock speed, or double threads but lower speeds and fewer cores? Let me know your thoughts!
It hinges on the amount of discussion, since newer components will always offer significant advantages for gaming. With these specifications, a fresh build seems optimal, or upgrading to an ROG Ally would be wise. You'll likely need to cap CPU power using the H310M board, and a K SKU could boost performance slightly. I wouldn't invest in that setup. You can also repurpose your existing RAM into an LGA1700 configuration. The 12600KF provides good value currently, around $150. Older boards were often available for under $100.
The 9700 offers more cores which benefits the tasks you mention. You'd also receive a Quicksync encoder by replacing the F CPU, which can be used with OBS. However, later generation chips provide significantly improved Quicksync performance.
Due to the high cost of used components, switching to an AM4 setup seems more worthwhile—especially if you secure good offers. You can find a B450 motherboard paired with a Ryzen 5 3600 for less than $150 today. This configuration should match the performance of an i7 while being cheaper and offering a stronger foundation. Keep this in mind.
Hey! I've been thinking about switching to AMD for a while now. Local prices aren't great, so I'm considering the new Ryzen 7 5700X with those extra cores for around $150. A used one would be about $100, but it's an international auction so it's a bit uncertain. Would you like some suggestions for compatible boards? You're eyeing the GIGABYTE B550M AORUS Elite on Amazon for $109, but you're leaning toward a new board instead. I understand you're cautious about used hardware and want something within your budget of roughly $100, preferably on Amazon or eBay for international shipping. Since you're planning to upgrade and maybe do some overclocking, a solid new board would be ideal. The Gigabyte A520M AORUS Elite is also on the list for $100, but I'm not sure about its performance. What do you think? Are you on the right track? Any advice would be appreciated!
The 5700X is an excellent chip—significantly superior to anything on your current setup in every aspect. If you can secure it for $100, that's a huge deal, and $150 is a reasonable amount. Regarding the board, unless you plan to upgrade to a Ryzen 9 model, the Aorus Elite mATX version isn't the best choice. In Hardware Unboxed's testing with a Ryzen 9 3950X overclocked, the PCB hit 118°C, which isn't ideal. Still, if you're limited to Ryzen 7 parts, it should work fine. The MSI B550-A Pro is available at the same price and performed much better in their tests—just 76°C after an hour. It also offers more features than the Aorus Elite, except it doesn't support WiFi. So, if WiFi isn't a priority, the MSI B550-A Pro is the better option in that price range.
Thanks for the update. I’m choosing this model instead. I’m really upset too. I was planning to pay for the new 5700x and finish checking out, but the sale closed just seconds before and it’s now $64.99. I wish I had looked at the cart earlier. Can I fix this? Would you suggest another cooler? I’m just tossing around options right now.
I’m considering the Deep Cool AK620, but I think it might be too expensive for this setup. A reviewer said a Thermalright FS140 is better and cheaper, so maybe it’s overpriced or too much for a 5700x. I’m curious if that’s the case. Do you know anything about coolers? I’d appreciate some advice since I’ve only used stock Intel ones and a few unmarked AIOs.
Edit: I’m looking into other recommendations now.
The Frost Spirit features a 140mm cooler, while the AK620 uses a 120mm model. Typically, a larger cooler offers improved heat dissipation due to increased surface area. Just ensure compatibility with your case. Hardware Canucks reviewed the Phantom Spirit alongside the FS140 and AK620 in a video, concluding the FS140 performed better. Their evaluation gives confidence in their testing. Regarding its low price, I’m uncertain—though the seller has a strong reputation with nearly 1,000 transactions, it doesn’t appear to be a scam unless the account was compromised.
