We’ve got already examined the present eighth gen Yoga Professional 7 14 (sometimes called the Yoga Narrow Professional 7 in reasonably a couple of markets) in a couple of other configurations — from the AMD processor (Zen3+) with an iGPU and a 2.5K show to the highest style with an Intel CPU, GeForce RTX 4050 Pc and an non-compulsory 3K panel. All variations of the subnotebook or multimedia pc have completed just right effects and Lenovo now additionally provides variations with the most recent Zen4 CPUs from AMD.
Our take a look at tool is the Yoga Professional 7 14APH G8 (82Y80020GE) with the Ryzen 7 7840HS together with the Radeon 780M iGPU, 32 GB RAM, a 1-TB SSD and a matte 2.5K panel. This configuration prices round US$1,300 or US$1,200 as a campus style. Optionally, you’ll be able to get the brand new Zen4 chip along the GeForce RTX 4050 Pc and a 3K panel for approximately US$1,650 (campus style: US$1,500) — on the other hand, simplest with 16 GB RAM.
On this assessment, we can most commonly be focussing at the new processor’s efficiency, in addition to the pc’s emissions and runtimes. For more info about its case, connectivity, enter units and audio system, take a look at our earlier critiques:
The pc’s matte IPS show with a facet ratio of 16:10 and a decision of 2,560 x 1,600 pixels is one we all know smartly from its predecessor, so we will be able to stay it brief. Subjectively, the 90-Hz panel’s image high quality stays superb, as content material is depicted sharply or even lighter spaces do not seem grainy. Moreover, its response speeds are just right and it does not employ PWM.
When it comes to brightness, the prevailing take a look at tool did minimally worse, with a median of 348 cd/m². In flip, its black price of 0.22 is a bit of higher, resulting in a greater most distinction ratio. In idea, on the other hand, those minor deviations are inside the standard vary of sequence manufacturing.
We measured the panel the use of the pro CalMAN device (X-Ceremony i1 Pro2) and the show already seemed respectable in its delivered state. Even though we famous a minimum blue tint and its colour temperature is a bit of at the cool aspect, this may simplest be noticed with the bare eye in direct comparability with a calibrated observe. On the other hand, its colour deviations in comparison to the sRGB reference have been already very small, simplest 100 % crimson was once above the vital deviation of three.
The usage of our personal calibration (profile is to be had free of charge obtain within the show field under), we have been in a position to reinforce those values total and right kind its slight colour tint, however its crimson deviation remained. Because of its whole sRGB protection, the panel continues to be appropriate for modifying photographs/movies.
Outdoor, the matte show made a tight impact — simplest direct daylight proved to be an excessive amount of for the pc’s most brightness and the display could not stay legible. The IPS panel’s viewing-angle steadiness is just right.
Lenovo provides its Yoga Professional 7 14 G8 with Intel’s new Zen4 CPUs and in comparison to the outdated style, the Ryzen 7 7840HS has now been blended with the devoted GeForce RTX 4050 Pc — previously, this was once reserved for the Intel variations. When it comes to RAM, this style continues to be afflicted by needless restrictions: Whilst our iGPU take a look at tool was once delivered with 32 GB RAM, the style with the GeForce GPU continues to simply characteristic 16 GB.
Within the pre-installed Vantage app, Lenovo provides other efficiency modes which will conveniently be decided on by means of the important thing mixture “Fn+Q”. As already noticed on its predecessor, it makes little sense to make use of the mode “perfect efficiency” (64/60 watts) at the style with the iGPU, because the ensuing added efficiency is beautiful low, whilst the lovers simplest spin louder. All over easy duties, you’ll be able to with a bit of luck depend on battery-saving mode (28/25 watts). We performed the next benchmarks and measurements the use of the mode “clever cooling” (28/25 watts). In overall, we famous relatively greater energy limits over the ones of its predecessor with the Ryzen 7 7735HS.
The AMD Ryzen 7 7840HS options 8 trendy Zen4 cores that may activity a complete of 16 threads directly and will achieve a most of 5.1 GHz. Its efficiency is very good in overall and (additionally due to its upper energy limits) it was once 20 % sooner all over the multi-core assessments and 12 % sooner within the single-core assessments in comparison to the Ryzen 7 7735HS with Zen3+ cores. Its multi-core efficiency was once additionally in a position to overhaul that of the contest that includes Intel CPUs (even the brand new Meteor Lake Core Extremely 7 155H), whilst the Intel chips have been relatively sooner within the single-core assessments.
Its CPU efficiency remained totally solid beneath everlasting load and in battery use. Additional CPU benchmarks can also be present in our tech segment.
In on a regular basis use, the Yoga Professional 7 14 with the Zen4 processor reacts temporarily and its artificial benchmark effects have been spectacular. All over the take a look at, we famous no problems with the tool.
All over our standardized latency take a look at (browsing the internet, 4K YouTube playback, CPU load), the take a look at tool confirmed no issues when it got here to the vital price “interrupt-to-process latency” — just one motive force had some problems. Consequently, the tool is definitely suited to real-time audio makes use of.
The 1-TB model of the Samsung PM9A1 is put in into our take a look at tool and after first booting up the tool, customers have 892 GB unfastened to make use of. The PCIe-4.0 power could be very speedy with most switch charges of over 7 GB/s, on the other hand, its efficiency does not stay solid beneath everlasting load, resulting in a lack of 50 %. At over 3 GB/s, its efficiency continues to be sufficient for on a regular basis use with none obstacles. Additional SSD benchmarks can also be discovered right here.
The Yoga Professional’s graphics card is the Radeon 780M, which on this case advantages from speedy LPDDR5x-6400 RAM in a dual-channel configuration and it is among the quickest Radeon 780Ms we’ve examined to this point. The iGPU is was once round 11 % sooner than the Radeon 680M all over the benchmarks, nevertheless it was once overwhelmed within the artificial assessments by means of the brand new Intel Arc GPU (8 cores) inside the new Meteor Lake cell processors. On the other hand, the 6 % hole between them isn’t too massive.
The iGPU is acceptable for on a regular basis use, together with taking part in again high-resolution movies, and its efficiency is even enough for the strange sport or two — even if you are going to generally must do with out taking part in the most recent video games. In much less tough video games, on the other hand, you’ll be able to frequently play the use of medium to excessive main points. In the true gaming assessments, the Radeon 780M additionally got here forward of the brand new Intel Arc GPU, even if we do not but have that many benchmark result of this style. In case you have larger gaming ambitions, you will have to select the Yoga Professional 7 14 G8 with the GeForce RTX 4050 Pc, even if you are going to then must do with out 32 GB of RAM.
The pc’s graphics efficiency stays totally solid beneath consistent load, which could also be the case in battery mode. Additional GPU benchmarks are to be had right here.
Total, the Yoga has turn into a bit of louder with the Zen4 processor, which could also be because of its greater energy limits. The lovers additionally get started up a bit of sooner in on a regular basis use than at the predecessor style. For those who are not looking for the total CPU efficiency, we might suggest the use of battery-saving mode in on a regular basis use. The values are nonetheless similar beneath low load, however the Zen4 style was once relatively louder whilst gaming and within the rigidity take a look at. In perfect efficiency mode, the utmost we measured was once 47.7 dB(A). There have been no different digital noises coming from the take a look at tool.
In idle mode and beneath low load, the pc’s floor temperatures are totally unproblematic. On the other hand, the bottom of the bottom unit turns into noticeably heat beneath load and we measured a most of just below 50 °C within the rear central house. Consequently, you will have to steer clear of pores and skin touch on this house. The highest of the bottom unit stays considerably cooler at a most of 42 °C, however your palms can even get hotter right here when typing. Within the rigidity take a look at, the Ryzen processor’s energy intake stabilized at just below 50 watts.
The Zen4 Yoga’s energy intake has greater in idle mode and beneath load, resulting in it attaining the 100-watt energy provide’s limits for a brief time period. All over the tension take a look at, its intake reasonably temporarily sank a bit of once more, on the other hand, it does not depart a lot area to rate the battery.
The tool’s 73 Wh battery capability has no longer modified, however its runtimes are worse than the ultimate AMD Yoga because of its upper power requirement. All over the WLAN take a look at with a brightness of 150 cd/m² and a refresh price of 60 Hz, we measured 10:18 hours (09:25 hours at 90 Hz) and 07:56 hours at complete brightness (07:39 hours at 90 Hz). Within the video take a look at, we famous 12:17 hours, resulting in the effects being shorter total than the Yoga with the Zen3+ processor.
Even after its transfer to the Zen4 processor from AMD, the Yoga Professional 7 14 G8 stays a very good multimedia pc and in lots of facets (case, connectivity, enter units, show), it hasn’t modified in any respect. The processor transfer from AMD Zen3+ to Zen4 brings extra efficiency (CPU in addition to iGPU), on the other hand, at the price of upper energy limits.
In on a regular basis use, this ends up in upper fan process, which do not need been totally vital. Right here, Lenovo may’ve graduated its efficiency modes extra obviously, as its efficiency values the use of clever cooling mode and perfect efficiency mode are nearly equivalent. The pc’s energy intake could also be relatively upper which, in flip, harms its runtimes.
The Zen4 processor from AMD might be offering extra efficiency however because of this, the Yoga Professional 7 14 G8 turns into louder and its runtimes don’t seem to be as just right.
For those who are not looking for the added efficiency and will make do with 16 GB RAM, then you’ll be able to for sure additionally opt for the variant with the Ryzen 7 7735HS, that includes relatively quieter lovers and longer runtimes — plus, you can save slightly of cash, too. In spite of everything, it’s certain that the Zen4 processor can now even be blended with the devoted GeForce RTX 4050 Pc, however on this case, Lenovo sadly limits the utmost RAM configuration to 16 GB, which merely does not make sense.
The Yoga Professional 7 14 G8 retails for round US$1,300. Whilst the model with the AMD processor cannot be discovered on Amazon, the model with an Intel CPU can also be discovered for US$1,299.
