Anyways, as they say it is better late than never, so you can install the app now and use to benchmark your devices. Still the app doesn’t support two high-level “Manhattan tests” on Windows Phone, it seems.
I put the app to test on my Lumia 1020 and the app performs just fine. It has tabbed UI and offers ability to selects tests or go ahead with all of them. It also neatly displays your device details and if you wish, you can compare your devices results to other devices for all the test you may have performed on your device.
You can register or login, if you already have an account. Though, registration sometimes doesn’t work smoothly and needs a fix.

GFXBench DirectX is a suite of high-level and low-level 3D graphics test that measures the performance of DirectX 11 (feature level 9 and 10) implementations on various Windows devices (Windows Phone 8.0/8.1, Windows RT, Windows 8.1).
• Manhattan test: GPU-intensive DirectX 11 test using advanced API-features for testing the latest high-end mobile devices (Features: multiple render targets for deferred rendering, geometry instancing and transform feedback, etc. Requires feature level 10.0)
• Battery and Stability test: Measures the device’s battery life and performance stability by logging frames-per-second (FPS) and expected battery running while running sustained game-like animations (the T-Rex scene).
• Render quality test: Measures the visual fidelity provided by the device in the high-end gaming-like scene
• Fully redesigned, multi-lingual, easy-to-use user interface: device comparison within the application by downloading the complete GFXBench database, extensive system information
