This Vivo X300 vs Realme GT 8 Pro comparison has a short answer, and it is not the one the camera crowd wants to hear. Buy the Realme GT 8 Pro. It is Rs 3,000 cheaper, it lasts longer, it charges faster, and its screen is sharper. The Vivo X300 is the better camera phone and the far nicer phone to carry. That is a real achievement. It is just not enough to win, because most buyers feel battery life and price every single day, and feel the last 5 percent of camera quality only on holidays.
Both phones sit in the same Rs 73,000 to Rs 76,000 lane, and both carry a 200MP camera. Read that twice, because the badge means opposite things here. On the Vivo it is the main camera. On the Realme it is the telephoto. That one detail tells you almost everything about who each phone is built for.
The price gap is small. The value gap is not
91mobiles lists the Vivo X300 at Rs 75,999 for 12GB and 256GB on Flipkart, with the 16GB and 512GB model at Rs 85,999. Gadgets360 agrees on the base price, listing Rs 75,998. The Realme GT 8 Pro starts at Rs 72,999 for the same 12GB and 256GB, per 91mobiles and Gadgets360, with the 16GB and 512GB at Rs 78,999. So the gap is Rs 3,000 at the base, but Rs 7,000 at the top end.
One honest caveat: 91mobiles and MySmartPrice currently show the GT 8 Pro out of stock. The price is real, but you may wait for a restock. If you need a phone this week, that flips the practical advice toward the Vivo.
Cameras: Vivo wins, and it is not close
This is the round Vivo built its whole phone around. The X300 carries a 200MP ZEISS main camera with a large 1/1.14-inch sensor and stabilisation, a 50MP ultrawide, and a 50MP telephoto with 3x optical zoom, per Gadgets360 and Digit. The front camera is 50MP with autofocus, a rarity that matters for group selfies and video calls.
The Hindu’s review is blunt: for imaging, the X300 “stands miles ahead of the OnePlus 15, Realme GT 8 Pro, and iQOO 15.” Notebookcheck agrees, calling the 200MP ZEISS camera genuinely strong.
Realme’s setup is no slouch. The GT 8 Pro has a 50MP main camera, a 50MP ultrawide, and a 200MP telephoto with 3x optical zoom, per 91mobiles and Gadgets360, plus Ricoh GR tuning and film presets. Its telephoto will out-zoom the Vivo at long range. But for the shots most people actually take, the main camera and the portraits, Vivo’s bigger sensor and ZEISS tuning win. The selfie gap is just as clear: 50MP against Realme’s 32MP. Camera winner: Vivo, decisively.
There is a jab here that Realme earned. The GT 8 Pro’s swappable camera module is fun for a week and forgotten by month two. Vivo spent its engineering budget on the sensor. Realme spent some of its on the accessory.
A small phone against a big one
Pick both phones up and the comparison changes shape. The Vivo X300 weighs 190 grams and measures 7.95mm thick, per Gadgets360 and BusinessToday, with a 6.31-inch 1.5K LTPO AMOLED display at 120Hz. This is a phone you can use one-handed on a crowded bus.
The Realme is a different animal: a 6.79-inch QHD+ AMOLED at 144Hz, per 91mobiles and Gadgets360, in a body around 214 to 218 grams depending on the source. MySmartPrice lists 7,000 nits peak brightness against the Vivo’s 4,500 nits, and 508 pixels per inch against the Vivo’s 1.5K panel. For films, games, and split-screen work, the Realme screen is simply better. Sharper, brighter, bigger.
Display winner: Realme, on resolution and brightness. Size and feel winner: Vivo, by a distance anyone with smaller hands will feel every day.
Performance is close. Stamina is not
Both chips are true flagships. The Vivo runs MediaTek’s Dimensity 9500, per 91mobiles and Gadgets360. The Realme runs Qualcomm’s Snapdragon 8 Elite Gen 5, per 91mobiles and Gadgets360. In normal use you will not feel a difference worth Rs 3,000, let alone Rs 75,000.
Push both hard and a gap opens. Notebookcheck warns the compact Vivo has a high potential for thermally induced throttling, which is the polite way of saying a small body sheds heat slowly. Realme pairs its chip with a large vapour chamber and gaming-first tuning, and Beebom’s review praises its excellent gaming performance outright. Performance winner, narrowly: Realme, for sustained loads.
Battery is where the Realme pulls away. It carries a 7,000mAh battery with 120W wired charging and 50W wireless charging, per Gadgets360. The Vivo carries a 6,040mAh battery with 90W wired and 40W wireless charging, per Gadgets360. The Hindu credits Vivo’s optimisation with a comfortable full day, but comfortable is not two days. Battery winner: Realme, clearly.
Software is the quiet round. Both phones run Android 16, Vivo with OriginOS 6 and Realme with Realme UI 7.0, per Gadgets360. Vivo promises 5 years of OS updates and 7 years of security patches for the X300, per Smartprix. Software winner: Vivo, on the update promise.
Vivo X300 vs Realme GT 8 Pro: the verdict
No fence-sitting. Category by category: price goes to the GT 8 Pro. Cameras go to the X300, decisively. Display goes to the GT 8 Pro. Sustained performance goes to the GT 8 Pro, narrowly. Battery and charging go to the GT 8 Pro. Size and feel go to the X300. Software support goes to the X300.
The overall winner is the Realme GT 8 Pro. Four rounds to three, and the four it wins are the ones most buyers feel daily: the price, the screen, the battery, and the charging speed. The Vivo wins the rounds that matter most to one specific buyer, and that buyer should ignore this overall verdict entirely.
Buy the Vivo X300 if photography is your phone’s main job, if you want the best compact flagship on sale in India right now, or if a 214-gram phone genuinely puts you off. The ZEISS cameras, the 50MP selfie camera, the one-hand size, and the long update promise make the Rs 3,000 premium easy to justify for that buyer. Our Vivo V80 review shows the same camera-first logic lower down Vivo’s range, and the X300 is that idea done properly at flagship level.
Buy the Realme GT 8 Pro if you game, stream, or just hate charging anxiety, and if you want the most phone per rupee at this price. Our Realme GT 8 Pro vs OnePlus 15 comparison already had the Realme beating a phone that now costs Rs 84,999, and our iQOO 15 review shows a rival that climbed to Rs 85,999 for the same chip. At Rs 72,999, the GT 8 Pro is the price anchor the whole segment is measured against.
One last note. If the GT 8 Pro is out of stock when you check, do not pay a scalper premium or jump to a Rs 85,000 rival in frustration. Wait for the restock, or buy the Vivo knowing you paid Rs 3,000 for better cameras and a smaller phone.
