HTC One (M8) for Windows vs Nokia Lumia Icon vs Lumia 635: specs comparison

HTC One (M8) for Windows vs Nokia Lumia Icon vs Lumia 635: specs comparison
Here comes one of the most intriguing Windows Phone devices ever built - the HTC One (M8) for Windows! We're sure that many Windows Phone fans are very excited now that HTC has announced the WP version of its flagship handset, but it goes without saying that there are some other options on the market to be considered before going for this metallic beast.

True, there aren't that many Windows Phone handsets right now to challenge the One (M8) for Windows, but if you're interested in this OS and are a US-based user, you should at least take a look at the Lumia Icon and the Lumia 635. The former is a high-end phone available through AT&T (keep in mind the the M8 for Windows will initially be a Verizon-exclusive), while the latter is a lower mid-range proposition that's available on both AT&T and T-Mobile. However, even though the Lumia 635 is in a very different category specs-wise, we think it does have a place in this comparison, since it can offer very similar functionality, along with a user experience that's not that bad at all.

How do these marvelous smartphones compare exactly? Maybe one has a faster processor, but the other compensates with a bigger battery? All the answers await in the following specs comparison!

Pixel density

Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. It’s measured in “pixels per inch”, or ppi. The higher the number, the more detailed and good-looking the display is.

441 ppi441 ppi218 ppi

Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.

Aperture size

Aperture size - The aperture of a camera is the opening through which light travels before it reaches the camera sensor. The smaller the number is, the bigger this opening is, allowing for more light to pass.

Focal length (35mm equivalent)

Focal length (35mm equivalent) - The lower (shorter) the focal length number, the wider the shot will be. Conversely, longer focal length cameras produce narrower frames, which can be used for telephoto (zoomed-in) purposes.

Camera sensor size

Camera sensor size - A bigger camera sensor is able to capture more light, and thus produce better photos.

Pixel size

Pixel size - The size of an individual pixel on a camera's sensor. The bigger, the better.

System chip

System chip - Most modern handsets use an advanced chip that includes many of the device’s hardware modules like the processor, Wi-Fi, Bluetooth and sometimes even the wireless radio. This field shows what particular system chip (or System-on-a-Chip) is used in the phone.

Qualcomm Snapdragon 801Qualcomm Snapdragon 800 8974-AAQualcomm Snapdragon 400

Processor - The processor is the main computing component of a phone and is a major factor when it comes to the overall speed of the device. Some more powerful smartphones use dual-core and quad-core processors designed to deliver greater performance.

Graphics processor

Graphics processor - The graphics processor is important for the smooth operation of the system and especially in games and other applications that may involve complex graphics and animations.

YesAdreno 330Adreno 305
System memory

System memory - System memory, or RAM memory is the type of memory that the device uses to temporarily store data from the OS or currently-running apps. The more RAM available to the device, the better the performance will be when multiple or heavier programs are running.

2 GB RAM2 GB RAM (Dual-channel) / LPDDR31 GB RAM
Built-in storage

Built-in storage - Bigger storage capacity allows you to keep more content saved onto your device, such as more applications, photos or video. Games and video content typically take up the biggest amount of storage space.

32 GB32 GB8 GB
Storage expansion

Storage expansion - Some handsets allow you to expand their storage capacity by using a memory expansion card – most often microSD. Expansion memory is mostly suitable for media storage, such as photo, video or music content.

Capacity - The bigger, the better! However, battery capacity is not the only factor that has an effect on battery life. Those include the chipset in use, the software running on the device, as well as the consumer's unique usage pattern.

CDMA - Code Division Multiple Access. A technique of multiplexing, also called spread spectrum, in which analog signals are converted into digital form for transmission. For each communication channel, the signals are encoded in a sequence known to the transmitter and the receiver for that channel. The foremost application is digital cellular phone technology from QUALCOMM that operates in the 800MHz band and 1.9GHz PCS band. CDMA phones are noted for their excellent call quality and long battery life.

I'm WP fan and I have to admit it looks worse with WP just because of how software buttons look on WP. I hate them in general but in Sense they are much prettier than WP.

I have to agree with you. Sense look alot better on M8 hardware. Rounded corner phone is kinda miss match for WP. I love those sharp edge designed WP device better. They match the look of tiles

I do side more toward Android.
But I also think the M8 looks better with Sense than with WP. I'm not much a fan of its hardware design, but it does go well with Sense.

Beauty is in the eyes of the beholder. No wp8 is not prettier. Ugly to me.

Besides Android has no fixed look. I can change a new look every day.
