Earlier this year, we looked at Acer’s new Swift 3 with AMD processor under the hood and we even reviewed the Ryzen 5 variant – which you can click here to read. A while back, AMD reached out and send us the AMD Ryzen 7 variant of the machine for us to play with and kind of their way of saying, “You were impressed with our Ryzen 5 U series, well wait till you try our Ryzen 7 U Processor.” With that happening, we have come up with a performance comparison with not just the Ryzen Processors but also its contenders to show much of a performance leap the Ryzen 7 offers.
If you want to know more about the look and feel of the Swift 3, check out our review where we covered everything.
To make these comparisons simple and straightforward – we relied on the following benchmarks: Cinebench R20, Blender, PCMARK 10 and 3DMARK. Since we no longer had the access to the Ryzen 5 variant of the Swift 3, we are pretty much limited with these benchmarks. Before we head to the comparison, let’s talk a bit about the Ryzen 4000 U Series processors. They use the TSMC 7nm FinFET Process to make the processor and its based on the Zen Architecture. Now the U series processor are the mobile processors which also comes with a Radeon Graphics.
AMD Ryzen 7 4700U vs Ryzen 5 4500U
In this case we are looking at two specific processors – the AMD Ryzen 5 4500U and Ryzen 4700U. Now these two processors have some interesting specification going on which you can see below.
From the looks of it above, you will notice that the only difference between both the processor is the core, thread count and the clock speeds which is marginal to say the least. But for what its worth, the very fact that both the processor has the same Default TDP coming in at 15W shows how power efficient these chips are and even with the cTDP range – 10-25W is still amazing. This paired with the core count and thread count shows that the process AMD rely for the 4000 Series is efficient as compared to the 3000 Series which used a 12nm process to make the processor and had lower the core count but higher thread count.
When we reviewed the Ryzen 5 variant of the Swift 3, we were genuinely surprised on how capable the laptop was – especially taking into consideration that the Laptop used a 5 Processor and still offered top of the line performance managing good thermals. The Ryzen 7 4700U lived up to our expectation and we expected to match or be marginally better than the 4500U, but it outperformed that.
In CPU intensive benchmarks where we pit both the processor against each other – like the Cinebench R20 – The performance difference on single core was just by a hair but it’s the multi core based work where the Ryzen 7 absolutely outshined the 5, just because it had two extra cores and thread count to give a better handling on multi-threaded workloads. Moving on to the infamous Blender BMW Render, we see similar performance with the Ryzen 7 finishing roughly by a minute earlier than the Ryzen 5. Moving on to benchmarks with both involvement of CPU and GPU like PCMARK 10 and 3DMARK Time Spy – you can see the difference where there’s 981 points difference in PCMARK 10 Extended and 111 points difference in Time Spy.
AMD Ryzen 7 4700U vs Intel Core i7-1065G7
We decided to compare the benchmark scores with the Intel Core i7 10th Generation-1065G7 – which was found in the ASUS Zenbook 13 we reviewed a while back. This is another proof that the Ryzen 7 slam dunks the Intel Core i7 Processor which was found in the Zenbook 13 any day because of its lower core count but still has the same thread count as the Ryzen 7 but heavily relies on a 10nm architecture. The Base frequency of the 1065G7 is at 1.30 GHz and max turbos at 3.90 GHz.
In terms of everyday use case, when it comes to stability – AMD Ryzen processor has come a long way with good power, memory, and performance management. Compared with the 3000 Series experience, the 4000 U Processors does feel a lot more refined.
All these while with team blue dominating the whole Desktop and Mobile space, AMD Ryzen has finally caught up and even surpassed with their offer and impressive performance to price, they have even captured a bigger and higher market share in both Mobile and Desktop chips during this pandemic. Not only AMD Ryzen 4700U in this case is a beast of a processor in a compact machine but it also brings a whole new array of options that are wallet friendly and bang for the buck.
We here at The Adventures of Vesper give the AMD Ryzen 7 4700U the Gold Award for being the most improved mobile processor in comparison to the Ryzen 7 3700U. Special thanks to AMD Malaysia for sending us the Acer Swift 3 for this review to happen.
