不過他說「I ran unity in chrome, but got 28xxx. I dont think it was accessing the gpu. I do have gpuz of the graphics card but it isnt much help」只測出了集顯的性能。 我用頂配 XPS 13（5500U）跑分，結果是這樣的：
補充新的測試，來自PCWorld Surface Book vs. MacBook Pro: It isn"t twice as fast. It"s three times as fast 這是SBook i5獨顯版對RMBP13 i5版的直接對比測試——注意SBook的i5版和i7版底座確實是可以交換的
That"s not a fair comparison, but I had a workaround. Microsoft had also provided a Core i5 Surface Book without discrete graphics. Microsoft is still pretty secretive about the GPU in the Surface Books, but I don』t believe it』s putting a different GPU in the higher-end models. I just plugged the Clipboard section with the Core i5 into the base with the graphics chip in it. Neat.
So for the record, I tested a Retina MacBook Pro 13 with an Intel Broadwell Core i5-5752U, Iris 6100 graphics, 8GB of RAM and PCIe SSD, and the latest El Capitan build. Its rival was a Surface Book with an Intel Skylake Core i5-6300U, GeForce graphics, 8GB of RAM and PCIe SSD with Windows 10.
The result is a bone-crushing blow for the MacBook Pro 13: Tomb Raider ran at a pathetic sub-24 fps, while the Surface Book whizzes along at 74 fps.
If Microsoft based its marketing statements on this test alone, it could have safely said 「triple the performance of a MacBook Pro.」
同時還測試了PremiereProGPU加速的結果
Premiere Pro has used GPU acceleration for years. It originally supported only Nvidia』s CUDA but has since added OpenCL. Luckily it runs on both platforms, too.
For my test I installed a Premiere Pro CC on both laptops, imported a 6.5GB 4K resolution .MOV video file, and then exported the movie to H.264 using the Vimeo preset at 1080p resolution with the maximum render quality setting enabled. On the Mac, OpenCL was used. On the Surface Book, CUDA was my choice because it』s an Nvidia chip.
The result? Another crushing blow in favor of the Surface Book. For a professional, less time spent rendering means more productivity. On the Surface Book, it was done literally minutes ahead of the MacBook Pro 13.
續航測試的結果顯示SBook獨顯版跟RMBP13確實是相同級別（SBook還稍微長點）
After 8 hours, I called it a day. The MacBook Pro 13 was reporting 19 percent battery life with 2 hours of estimated battery life left. The Surface Book was reporting 29 percent with 2:26 left. I could have taken both down to zero, but I wasn"t going to sit in my cubicle and watch the moon rise.
I give the Surface Book the win by a small margin. What"s really impressive is the Surface Book does it with a touch-screen which can consume 10 percent of run time and a smaller battery too. Both laptops actually offer fairly excellent run time overall but neither would have hit their rated life for lower-resolution file playback.
If you add both together, that gives the MacBook Pro 13 about 9:41 of playing 4K content with the Surface Book running for 10:37. This isn"t an ideal battery run down test condition but probably realistic as plenty of people turn off their computers during take off and then turn them back on in the air. The win clearly goes to the Surface Book but both get kudos for long video playback performance.

上周被鸛狸猿硬點，去天堂給慘死菲律賓的Richard.F.Heck老先生過了一周的柱子，現在回來答這個問題。 測試結果出來了，一切塵埃落定 一句話——殺雞焉用牛刀，對付RMBP13這種貨色哪用得著那麼高端的顯卡啊 Surface Book Review: Beautiful, Blazing, Buggy
再補充其他幾個測試：
Microsoft Surface Book Review 那個i5獨顯的測試疑似是寫錯了（很明顯FS測試仍然是集顯的成績，但是後面那個SD卻是獨顯的成績，很奇怪）
這是SP4的——SB的現在暫時沒有，不過這次二者用的是同樣的硬碟 Graphics and NAND Performance
這是RMBP13的——知乎上已經有討論過了，2015款MacBook全家4K性能都低得不正常
RMBP13勉強贏回一局，不過兩者差距不大 屏幕暫時沒有詳細的對比測試，不過Engadget評價也很高 Surface Book review: the ultimate laptop, even if it isn"t perfect
Whether you use it as a laptop or tablet, the display is as gorgeous as you"d expect on something billed as the ultimate laptop. With a pixel density of 267 ppi, it"s even crisper than both the Chromebook Pixel (239 ppi) and the 13-inch Retina display MacBook Pro (227 ppi), and even those make it hard to pick out individual pixels. Aside from the resolution, you"re looking at some rich, but not overbearing colors, with a wide palette that covers 100 percent of the sRGB spectrum. And though the glossy screen finish wasn"t immune to sun glare, I found it mostly stayed readable in different conditions, including my office, where I sit next to an east-facing window that lets in lots of light every morning.
2，由於 Surface Book CPU 是做在極端輕薄的 Clickboard 部分的。為了保證散熱，CPU 只能用低壓 U，而且由於核顯和獨顯是共用散熱模塊的，核顯 GPU 會佔用一部分 CPU 的散熱空間導致 CPU 估計不能保持長時間滿載狀態（傳說中的降頻）。獨立顯卡的作用應該更多是釋放出這部分散熱空間，以保證 CPU 部分長時間高頻運作的散熱。
3，Surface Book 是完美外置顯卡筆記本形態的一個開拓者而已，而且這是第一代，PCI-E匯流排介面外露才是其最具殺傷力的地方，不排除之前某問題里有人提的那樣，說不定下一代只有一個 帶 PCI-E 介面的13寸無邊框 Surface Pro（筆記本用無邊框狀態，平板用邊框狀態，參考 intel 的 Smart Frame），自行選擇 type cover / 電池底座 / 各種配置的 顯卡+電池底座。
之所以會說surface book是4核，著實不是某些軟粉的腦補，而是微軟發布會上，Panos Panay說了一句： "With two more cores and dGPU, surface book can be two times powerful than mac pro" 所以，要麼是微軟自己搞錯了，要麼就是軟粉的聽力沒學好。說句實話，surface book之所以那麼招黑，除了那些一夜之間多出來的軟粉和個彆強行洗地的狂熱教徒之外，更主要的是微軟過度宣傳的問題。發布會上玩的文字遊戲太多，導致現在詳細參數被曝光後打臉打得停不下來。所以說， 不能老想自己搞個大新聞，不然將來顧客的腦補和現實出了偏差，微軟也是有責任的。
