How do the 7940HX and 57X3D compare?
I'm thinking about switching to Minisforum's BD790i SE now that it's on sale for gaming purposes. The 7600 seems pretty similar, but the 5700X3D might be slightly quicker in most games, especially at higher performance levels. The 7940HX on the ITX board looks capable of running smoothly up to around 5GHz thanks to its good cooler, which should boost its speed significantly compared to the 5700X3D. With 16 Zen 4 cores capped at 70W, it could really perform better if everything works well. What are your thoughts?
It really depends on the task at hand. For your 3070 in gaming, you're unlikely to see a big difference. If you're handling multiple cores for things like rendering, you might notice some improvement. Ultimately, it boils down to your specific needs and goals.
On Ryzen 7945HX and 7845HX, performance gap is just 10%. Comparing Ryzen 7900 vs 7940HX shows similar differences. Budget Asrock boards around 140 EUR often include Ryzen 7900 with a board. I’d consider getting the 7900 later if needed. Updated pricing info included.
A few months back, before the Ryzen 7000 X3D price fell, those laptop CPUs seemed reasonable. For example, the 7945HX was priced similarly to the bare 7950X CPU. Nowadays, it's tough to say—prices hover around 50-60 euros when you compare a desktop CPU with an ASRock A620i board, which can handle a 170-watt CPU continuously.
Yes, the 7800x3D+ITX board matches the MinisForum price, yet it offers significantly better performance in gaming.
plus the ability to upgrade the CPU and you can even customize it if you wish. I don’t think these SFF boards make sense for laptops unless they’re much cheaper or smaller than what you need, like the ASRock desktop mini units. If you don’t plan to use a dedicated GPU now, it might be better to get a full PC instead. With Zen 5 APUs, there are even more powerful options available, and if you need a GPU, just build a standard setup like everyone else does.
Currently, the Ryzen 7940hx motherboard+CPU bundle is on sale for a significant discount. At 16 cores priced at $360, it offers great value for those who need high performance. However, using laptop So-Dimms limits your options since they’re slower and have power constraints of 90-100W. This deal is appealing only if you have demanding workloads that require maximum efficiency, otherwise it may not be the best fit. I’m considering adding one to my cart because of its unique value at this price point.
Approximately a few months back? Prior to the Ryzen 9000 launch, the Ryzen 7800X3D was priced identically to the Ryzen 7900, whereas now it's nearly the same as the 7950X.
I'm sorry, but I only see the 7945hx offer, not the 7940hx one. The 7700x + ITX board could be a better fit. Personally, I tend to steer clear of mobile chips for desktop use—they have their place, but once you commit, it's all set.
