Zen 4 dùng dây chuyền khác cả CCD lẫn IOD thì lượng lớn wafer 12nm từ giờ tới 2014 để làm gì vậy? VGA 14nm thì còn ko có hàng nữa là. CPU 4 nhân giá rẻ vẫn bán đc mà.
thảo luận AMD Ryzen 7000 “Raphael” Zen4 IHS design for AM5/LGA1718 package has been leaked
- Thread starter Christmas.
- Start date

Đã tốn tiền
Tdp per mà vẫn thế có khi lại giã cho các anh chê amd nóng khó tản nhiệt nát họng

Đã tốn tiền
ngang Zen 2 mà giá rẻ là ngon lắm rồi
kiểu 4350G = 10100F

Cái nắp ngầu thế mà chê.Nhìn cái ihs như đấm vào mắtchắc chỉ là 1 trong những nguyên mẫu thôi chứ làm thật thì tôi chửi bỏ mẹ bọn thiết kế

AMD đem Smart Access Memory lên các VGA Radeon RX 5000
Với Windows 11 chuẩn bị ra mắt, AMD đã giới thiệu các tính năng game mới trên dải sản phẩm Radeon, và tích hợp ngược lên những sản phẩm cũ hơn – RX 5000.
Bản cập nhật driver mới nhất Radeon Adrenalin 21.9.1 đem lại khả năng hỗ trợ Smart Access Memory (SAM) lên các card đồ họa AMD Radeon RX 5000 kết hợp với Ryzen 5000 hoặc thậm chí là Ryzen 3000.

ông giáng sinh đó post rải bài khắp nơi đó. 1 post làm 2-3 Thread rồi post khắp các thread khác nữa^ Update này thì cho bên thớt VGA AMD RX 5k chứ

Vulkan Ray Tracing is now available to AMD Pre-RDNA2 GPUs through Linux Mesa software implementation
AMD Navi 1X, Vega, and Polaris GPU might support ray tracing through this software implementation
Everything can be done with simple shaders, just not everything will be just as fast.
There is a reason why NVIDIA has RT Cores and AMD introduced Ray Accelerators with their RDNA2 architecture. This type of core is specifically designed to accelerate bounding volume hierarchy (BVH) instructions, which are used to find collisions between rays in a graphics scene. This complex tree structure requires a lot of computing power, thus GPU makers have designed custom cores specifically designed to solve this issue at a much faster speed. Algorithms not accelerated by ray tracing cores will obviously work slower and the end result will probably be less appealing, at least when real-time graphics are considered.
Mesa, which is an open source implementation of OpenGL & Vulkan API for Linux, has just received an update that might introduce ray tracing support to AMD GPUs that lack Ray Accelerators. Developer Joshua Ashton claims that this technique will work for AMD Navi 1X, Vega, and Polaris GPU.
This PR implements ray-tracing for older generations (Navi, Vega, Polaris, etc.)
It does this by emulating the AMD bvh intersection instructions in software.
Right now this passes CTS the same as on RDNA 2 cards.
— Joshua Ashton
Users have already reported that even Quake II RTX works with this Mesa merge request, but the game needs to be built from the source and the Steam version does not work.
We have recently heard from Ubisoft that they adopted ‘hybrid ray tracing’ into Far Cry 6, which means that the algorithm uses both the shaders and ray tracing cores to achieve the final result. It is unclear though if this implementation requires both cores to be present in the GPU core. However, it is clear that game developers are slowly realizing that ray tracing acceleration can be done in a different, but not always as efficient, way.
