Brand: Lenovo

The 4K Ice Lake difference. 4K ekran için daha ucuz FHD seçeneğine birkaç ekstra Benjamims harcamaya değer mi? 4K SKU, pil ömründe ölçülebilir bir kesimin yanı sıra hem daha derin renkler hem de daha parlak bir ekran sunuyor.

14 inç Yoga C940, geçen yılki 13.9 inç Yoga C930'un doğrudan ardılı. Ekran boyutundaki küçük yumru dışında, yeni model, burada FHD SKU'yu ilk incelememizde ayrıntılı olarak açıklandığı gibi bir dizi küçük değişiklik getiriyor. Bu inceleme, FHD ve 4K seçenekleri arasında ne tür iyileştirmeler veya farklılıklar bekleyebileceğimizi görmek için 4K UHD SKU'ya odaklanacak. Ekran farklılıklarından başka, 4K SKU'muzla ilgili her şey FHD SKU ile aynı kalıyor ve bu yüzden kontrol etmenizi öneririz şasi ve özellikleri hakkında daha fazla bilgi edinmek için mevcut incelememizi inceleyin. Yoga C940'ın 15.6 inçlik sürümü daha hızlı Core H serisi CPU'lar ve GeForce Max-Q grafikleriyle de kullanılabilir. 14 inç Yoga C940, HP Spectre x360 13, Dell XPS 13 gibi diğer amiral gemisi alt defterleri ve dönüştürülebilirleriyle doğrudan rekabet eder 7390 2'si 1 arada, Asus ZenBook Flip 14 ve Microsoft Surface Book serisi.Daha fazla Lenovo yorumu: Lenovo Yoga C940-14 (FHD) Lenovo Yoga C940-15Lenovo Yoga C930Lenovo ThinkPad P53Lenovo Legion Y740

Bakım

Alt panel T5 Torx vidalarla sabitlenmiştir ve şasiye zarar vermeden çıkarılması çok zordur. Keskin kenarlar keskin bir kenarla bile çok sıkıdır ve son kullanıcı için düşmanca servis sağlar.

Görüntüle

Yerel 4K UHD çözünürlüğe sahip 14 inç ekranlar nadirdir ve bu nedenle bu Lenovo'daki BOE HF NV140QUM-N54 IPS panelinin şu ana kadar veritabanımızda başka hiçbir dizüstü bilgisayarda bulunmaması şaşırtıcı değildir. Bununla birlikte, panel diğer Ultrabook'ların çoğunda daha yaygın olan Sharp, AU Optronics veya LG Philips panellerine kıyasla daha iyi bir şekilde karşılaştırır. Kontrast gibi temel özellikler, derin renkler, net metinler ve makul yanıt süreleri ile 1500: 1'den fazla mükemmeldir. Tek büyük şikayetimiz, HP EliteBook 1040 G5'te 120 Hz ile karşılaştırıldığında 60 Hz yenileme hızı ile sınırlı olmasıdır. Belki de ekranın en önemli özelliği parlaklığıdır. Lenovo, hem FHD hem de 4K UHD SKU'ları için 500 nit talep ederken, FHD test birimimizde sadece 384 nit ölçebildik. Neyse ki, bu 4K UHD birimi, Lenovo'nun geçen yılki Yoga C930'un çok üstünde ve rakip XPS 13 7390 2'si 1 arada ile eşit olduğunu iddia ettiği kadar parlak.

* ... smaller is better

Tam AdobeRGB kapsamının mümkün olduğu Sharp IGZO panelleri kadar geniş olmasa da, renk alanı FHD panelinden daha geniş (yüzde 74'e karşılık yüzde 62 AdobeRGB). Yoga C940 SKU'sundan bağımsız olarak tam sRGB kapsama alanı sağlandığından, biraz daha derin renkler günlük kullanımı önemli bir şekilde etkilemez.

X-Rite kolorimetresi ile yapılan diğer ölçümler, aşırı sıcak bir renk sıcaklığı ve kutunun dışında zayıf RGB dengesini ortaya çıkarır, bu da panelin daha doğru renkler yapabileceğini biliyoruz. Ekranı kendimiz kalibre etmek hem gri tonlamayı hem de renkleri sırasıyla 8.1 ve 5.48 ortalama DeltaE değerlerinden sırasıyla 0.8 ve 2.22'ye önemli ölçüde geliştirir. Dizüstü bilgisayardan en iyi şekilde yararlanmak için ekranı kalibre etmenizi veya yukarıdaki ICM profilimizi uygulamanızı öneririz.

Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

↔ Response Time Black to White
27.2 ms ... rise ↗ and fall ↘ combined	↗ 15.6 ms rise
27.2 ms ... rise ↗ and fall ↘ combined	↘ 11.6 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 65 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.5 ms).
↔ Response Time 50% Grey to 80% Grey
44.4 ms ... rise ↗ and fall ↘ combined	↗ 22.4 ms rise
44.4 ms ... rise ↗ and fall ↘ combined	↘ 22 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 72 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (33.7 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured.

4K test ünitemiz, daha iyi dış mekan arkadaşı olmak için son FHD ünitemizden daha parlaktır. Yine de, parlak ekran nedeniyle doğrudan güneş ışığından kaçınmak ve yazı tipi ölçeklendirmesini artırmak en iyisidir. Dönüştürülebilir açık havada sık sık kullanmak istiyorsanız 1000 nit HP EliteBook veya Dragonfly'i düşünün. Görüş açıları, bir IPS panelinde olduğu gibi geniştir. Portre modundayken daha büyük 15,6 inç Yoga C940'a kıyasla renklerin ve parlaklığın daha kararlı olduğunu unutmayın.

Verim

CPU ve RAM FHD SKU'muzla aynı kalırken, bazı 3DMark sorunlarını çözmek için Intel grafik sürücüsünü 25.20.100.7014 DCH olarak güncelledik. Bu nedenle, bu sefer 25 W Core i7-1065G7'nin ham performansının daha eksiksiz bir resmini çizebiliyoruz.

İşlemci

İşlemci performansı en çok son nesil Core i7-8565U veya mevcut Zen Ryzen 7 3700U'ya benziyor, çünkü Ice Lake ham CPU performansı yerine gen-gen GPU iyileştirmelerine odaklanıyor. Ancak, performans sürdürülebilirliği biraz daha iyi olabilir; CineBench R15 Multi-Thread'ı bir döngüde çalıştırırken, puanlar yüzde 18'lik bir performans düşüşünü temsil etmek için zamanla 750 puandan 615 puana kadar düşecektir. Sonuçlar hala Razer Blade Stealth GTX 1650 Max-Q'da bulunan aynı CPU'nun 15 W sürümünden çok daha iyi. Daha fazla teknik bilgi ve kıyaslama için Core i7-1065G7'deki özel sayfamıza bakın.

GPU Performance

As mentioned before, 3DMark benchmarks paint a very different picture from real-world gaming performance. While 3DMark scores are within single-digit percentage points of the Radeon RX Vega 10 and about 20 to 27 percent behind the GeForce MX250, performance in games can vary wildly. Shadow of the Tomb Raider, for example, is 30 to 40 percent slower than the RX Vega 10 and MX250 while frame rates in Rocket League are more comparable. If you plan on doing any gaming at all, then your best bet is to stick with undemanding titles like Rocket League, Fortnite, or LoL where performance will be more reliable.

Performance will always be significantly faster than the last generation UHD Graphics 620 that the Ice Lake series replaces by at least 2x in most cases.

See our dedicated page on the Iris Plus G7 for more benchmark comparisons.

Emissions

System Noise

White: Background, Red: System idle, Blue: 3DMark 06, Orange: Witcher 3, Green: Prime95+FurMark

Fan noise is generally quiet at about 29 to 33 dB(A) when under most conditions. However, an annoying pulsing behavior occurs when under higher loads like gaming. For example, fan noise will steadily rise and fall between 31 dB(A) and 40.7 dB(A) when running Witcher 3. We would have preferred a fixed RPM to be more inconspicuous during gameplay.

Our unit exhibits slight electronic noise when placing an ear near the keyboard keys.

Stress Test

We stress the system to identify for any potential throttling or stability issues. When running Prime95, the CPU can be observed boosting up to 3.5 GHz for the first few seconds before eventually falling to 2.9 GHz for the next 30 seconds. CPU temperature would remain stable at about 96 C during this period. Thereafter, clock rates and temperature would drop and cycle indefinitely between 2.3 to 2.4 GHz and 77 C to 81 C, respectively. It's not surprising that the convertible is unable to maintain very high Turbo Boost clock rates for very long periods considering the form factor and what we observed during our CineBench R15 loop test above.

Running Witcher 3 results in a stable GPU clock rate of 1050 Hz and a core temperature of 77 C compared to 85 C on the XPS 13 7390 2-in-1 with the same CPU. Running on battery power will reduce performance just slightly; a 3DMark 11 run on batteries returns Physics and Graphics scores of 9687 and 4502 points, respectively, compared to 10494 and 4594 points when on mains.

	CPU Clock (GHz)	GPU Clock (MHz)	Average CPU Temperature (°C)

Prime95 Stress	2.3 - 2.4	--	77 - 81
Prime95 + FurMark Stress	1.2 - 1.3	850	70 - 72

Energy Management

Power Consumption

Idling on desktop will demand between 5 W and 12 W compared to just 3 W and 9 W on the FHD option likely due to both the brighter display and higher native resolution of our 4K unit. Consumption is consistently higher during higher processing loads as well which will impact battery life as shown in our next section.

It's worth noting that power consumption when gaming on the Lenovo is about 16 percent less than the Huawei MateBook 14 with GeForce MX250 graphics while GPU performance is roughly 20 to 27 percent behind according to 3DMark benchmarks. In other words, performance-per-Watt is not necessarily greater on Intel's integrated chipset when compared to the more common discrete Nvidia and Intel solution especially since gaming performance is generally more inconsistent on the Ice Lake Iris platform.

We're able to measure a maximum consumption of 64.6 W from the small (~10.8 x 4.7 x 3 cm) 65 W AC adapter immediately after initiating Prime95 for 100 percent CPU utilization. This high of a consumption is sustainable for just a few seconds before falling to just 35 W after 5 full minutes of stress as shown by our graphs below. We wouldn't be observing declining power consumption over time had the laptop been able to maintain maximum Turbo Boost indefinitely.

Power consumption while running the first benchmark scene of 3DMark 06

Power Consumption while running Witcher 3

Prime95 initiated at 10s mark. Note the initial spike up to 64.6 W and subsequent drops mirror our Prime95 and CineBench loop test observations above

Prime95+FurMark initiated at 10s mark. The fall after the initial consumption spike is steeper than Prime95 alone

Battery Life

A battery deficit is expected when compared to the FHD SKU. Our 4K unit would shut down after approximately 7 hours of real-world WLAN use to be about 3 hours shorter than the FHD version. Both laptops were subjected to the same 150-nit brightness setting and Balanced power profile while looping various web pages at identical intervals.

Charging from empty to full capacity takes about 2.5 hours to be slower than most Ultrabooks where 1.5 hours is more common. The included USB Type-C charger can also be used to charge smartphones, Switch consoles, and other compatible laptops.

Verdict

In review: Lenovo Yoga C940-14IIL 81Q9. Test model provided by Lenovo

Opting for the 4K UHD Yoga C940 instead of the less expensive FHD SKU will bring some advantages and disadvantages. The good news is that the higher native resolution allows for finer pen inputs, slightly deeper colors, and a measurably brighter backlight than the FHD SKU without impacting response times or contrast by very much. Colors and grayscale are curiously not as accurate out of the box, but an end-user calibration addresses this.

The main drawback of the 4K option is its shorter battery life by about 3 hours according to our measurements and slightly higher power consumption levels. Even so, 7 hours of real-world WLAN use should be more than enough for most users. All Yoga C940-14 SKUs share the same disadvantages when it comes to the difficult serviceability, pulsing fans when gaming, and highly variable gaming performance of Ice Lake.

The business-centric HP EliteBook x360 1040 series has more connectivity options, brighter displays, and slimmer designs for a higher starting price than the Lenovo Yoga C940-14. If you want a more balanced 14-inch consumer convertible without settling for the smaller 13.3-inch Spectre x360 or 13.4-inch Dell XPS 2-in-1, then the Yoga C940 should be on the top of your list.
