Blog en direct de l'événement de lancement de la carte graphique AMD Radeon RDNA3: RX 7000 Series, Performances de nouvelle génération
20:01 UTC: AMD’s roadmap is supremely busy:
20:02 UTC: “today it’s all about gaming”
20:03 UTC: AMD covers practically every gaming form-factor right now.
20:04 UTC: Lisa named 5800X3D, the company is definitely manufacturing more.
20:05 UTC: ARNDR3: World’s first chiplet gaming GPU:
20:06 UTC: Graphics Compute Die on 5 nm, Memory Controller Dies on 6 nm
20:07 UTC: 61 TFLOP/s compute power. That’s nearly 3x over the 23 TFLOP’s of the predecessor
20:08 UTC: here it its, le Navi 31:
20:08 UTC: 54% perf/W gain, similar to that of RDNA2 vs RDNA
20:09 UTC: Le renouvellement de la marque Silent Hill fait allusion au retour de la franchise, le RX 7900 XTX et RX 7900 XT:
20:09 UTC: 300 mm2 GCD, 6x 37 mm2 MCDs, graphics-relevant Infinity Fabric
20:11 UTC: Each MCD has 16 Mo de cache Infinity, and 64-bit memory path. Together, le Navi 31 has 384-bit GDDR6 memory I/O. Peak bandwidth to 5.3 To/s
20:12 UTC: This is the all-new compute unit, avec 64 dual-pumped stream processors, AI accelerators, and new-gen RT accelerator (50% RT performance)
20:13 UTC: 2.7X AI performance uplift with the AI accelerators.
20:15 UTC: Radiance Display Engine: The GPU gets DisplayPort 2.1 native support: 4K @ 480 Hz possible, 8K at 165 Hz possible, with a single cable.
20:16 UTC: Dual Media Accelerator Engines
20:17 UTC: RDNA3 reintroduces decoupled clock domains, with shaders running at a different frequency than the front-end:
20:18 UTC: 61.6 TFLOPs peak throughput
20:18 UTC: Architecture design goals met:
20:19 UTC: RX 7900 XTX is designed for 4K
20:20 UTC: 70% performance uplift over RX 6950 XT!
20:21 UTC: The card is surprisingly compact.
20:21 UTC: 355 W board power, just two 8-pin
20:22 UTC: RX 7900 XT
20:22 UTC: DisplayPort 2.1 allows you to actually play at 4K @ 480 Hz
20:24 UTC: Samsung unveils an 8K Ultrawide for CES
20:24 UTC: 8K @ 165 Hz possible
20:26 UTC: 96 FPS AC: Valhalla at 8K!
20:27 UTC: Halo Infinite to get Ray Tracing
20:27 UTC: Ray Tracing Performance is +60% over the previous generation:
20:28 UTC: Oh joy, a tech demo:
20:30 UTC: AMD FSR3 with Fluid Motion Frames announced: DLSS 3-like frame generation: Venant 2023
20:32 UTC: En résumé:
20:37 UTC: Hyper-RX unifies Boost and Anti-Lag into a single one-click feature:
20:41 UTC: SmartAccess Video leverages video-acceleration of both the GPU and the Ryzen 7000-series iGPU:
20:34 UTC: AMD Advantage coming to pre-built desktops, combine RX 7000-series with Ryzen 7000-series processors:20:42 UTC: AMD is aggressively pricing the Radeon RX 7900 XTX at $999, et RX 7900 XT à $899, both available from December 13
