日本AMD Ryzen 7 4800H vs AMD Ryzen 7 3750H – that is brutal 120% progress
Ok, as soon as we had our hands on the leaked results regarding the upcoming Zen 2 CPUs we compared 4800H and 4800U with a lot of Intel CPUs – i9-9980HK, i9-9880H, i7-9750H, and i7-1065G7. At least for now, the still unreleased Zen 2 processors look like extremely good performers – no chance for the current-gen Intel CPUs because 4800H has a bit higher scores even than i9-9980HK and 4800U just crushed i7-1065G7.
It would be a bit unfair if we don’t compare the results of Zen 2 with our own Zen+ data that we’ve gathered while testing AMD-powered laptops. The AMD Ryzen 7 3750H is the best performer among the Zen+ mobile processor. As we already know from our previous comparisons the latter is close to the i7-8565U performance and it’s a lot slower than i7-9750H.
We are sure that our readers know that 3750H is slower than 4800H but the question is how big is the gap between them? Let’s find the answer.
Of course, as soon as we get our hands on the new Ryzen CPUs, we’ll update this article with results from our own lab.
Quick Specs
The 4800H has double the core count (8 vs 4 cores, 16 vs 8 threads), double the cache size (8MB to 4MB), and it supports memory sticks with almost two times higher frequencies (LPDDR4X-4266MHz to DDR4-2400MHz) than 3750H. “Poor” Zen+ CPU – no chance for it, mark those words. In terms of frequencies (which actually doesn’t matter anymore after the specs comparison in the last sentence), the Zen 2 CPU has higher base and boost clocks than its Zen+ rival – 2.90 GHz – 4.20 GHz vs 2.30 GHz – 4.00 GHz. The future AMD CPU has higher TDP values but it’s normal – so much power needs more “space”.
Ok, let’s go further and we’ll see how many times 4800H is faster than 3750H.
More detailed specs here – AMD Ryzen 7 4800H / AMD Ryzen 7 3750H
Specs table:
| AMD Ryzen 7 4800H | AMD Ryzen 7 3750H | |
|---|---|---|
| Cores / Threads | 8 / 16 | 4 / 8 |
| Base / Max frequency | 2.90 – 4.20 GHz | 2.30 – 4.00 GHz |
| Cache | 8 MB L3 Cache | 4 MB L3 Cache |
| TDP / up / down | 45W / 54W / 35W | 35W / 35W / 12W |
| Memory support | DDR4-3200MHz; LPDDR4-4266MHz | DDR4-2400MHz |
CPU Benchmarks
The answer – 4800H is over two times (+120%) faster than 3750H in 3D rendering.
Results are from our Photoshop benchmark test (the lower the score, the better)
GPU Benchmarks
The same story here – the unreleased Vega 7 has much faster CUs than Vega 10 and that’s why the latter is a lot slower.
| AMD RX Vega 7 | AMD RX Vega 10 | Difference | |
|---|---|---|---|
| 3DMark Firestrike | 5068 | 2288 | 122% |
Verdict
At last – AMD (will) have superb mobile processors when compared to Intel. No, don’t get us wrong – the Zen+ processors aren’t bad. They are efficient and fast but when they are compared to their direct rivals from Intel they don’t look that fast (because they aren’t). AMD didn’t have a proper “answer” to Intel’s 6 and 8-core Coffee Lake monsters. Soon, they will release a lot of worthy competitors that are faster even than 9980HK. The AMD Ryzen 7 3750H is part of the road which AMD had to walk before Zen 2. The 3750H is still a good buy because the machines configured with it are good deals right now.
We almost forgot the main topic of this comparison – the 4800H is a lot faster than the current performance CPU king of AMD. Two times the computing performance over 3750H and two times the iGPU performance over the RX Vega 10! Good job AMD, that is what we call proper progress. AMD will force Intel to evolve faster because the new Zen 2 CPUs look (and they probably are) monstrous performers and right now it looks like Intel are in а catching up position.
Of course, as soon as we get our hands on the new Ryzen CPUs, we’ll update this article with results from our own lab.
